Icebergs broken off from glaciers drift south on the east Greenland current. Evidence of Arctic warming is present in widespread melting of glaciers and sea ice. Melting of reflective snow and ice will reveal darker land and ocean, which will increase our planet's absorption of heat. This could lead to a feedback loop of further warming and melting.

A couple weeks ago I posted on the difficulties of spotting Oophaga lehmanni in the wild, and its threatened status (www.facebook.com/paul.bertner/posts/1954323497983506). After deliberating for a week, while cooped up with the flu and a sprained finger, and rummaging online for records of O. lehmanni, I was struck not only by the overall dearth, but by the almost complete lack of 'in situ' images, with not a single one illustrating behaviour or a decent representation of the environment. For a critically threatened species, one whose risk of extinction is quite high, this to me represented a tremendous oversight. Though I'd already tried and failed to capture some behaviour shots on a short previous expedition, I decided to dedicate a week to the endeavour, if for no other reason than to have a record befitting such an elegant species.

 

Travelling to the same site as before, I settled in to photograph calling behaviours. Setting aside a week to get this rather modest shot was giving myself quite a lot of latitude I thought...I was wrong. Three days in and I had little to show for my efforts, resorting to shooting at 300mm + 1.4X TC, I was still struggling to surprise this elusive gem. Though I could hear the frogs calling, and could even see them doing so, creeping up on them and getting a respectable photo was proving an altogether different kind of a problem.

 

I tried remote shooting (however they rarely returned to the same perch, causing the framing to be off), I tried hides (though after waiting 2-3hrs in mosquito infested areas with the slightest movement causing the frogs to go diving back into root tangles proved frustrating to say the least). Nothing seemed to work, and I was beginning to despair.

 

This begged the question, "Why would a poisonous species which supposedly has no known predators be so timid?" The answer somewhat surprised me, "researchers". Apparently the frequent capture-release monitoring of the local populations has resulted in a rather poignant behavioural change. A species which would otherwise be fearlessly hopping the rainforest understory has had its buzzing call muted. It was a potent reminder of our influence on the natural world, whether it represents a kind of Schroedinger's cat problem, in which our very observation and monitoring of a species ultimately impacts its natural behaviours, or whether it's something more intrusive or sinister like manipulation for an aesthetic image or poaching, respectively.

 

We have to go further in I told the guide. And so we walked, and we walked and still the frogs fell silent at the sound of our approaching footfalls. 6 hours later, 2 of which we left the already weedy trail completely to bushwhack, and we came to a spot where we crept up upon a calling frog. It continued its buzzing call despite undoubtedly having already seen us. I made sure to shoot without flash and with a long lens to prevent any kind of potential habituation/aversion. Moments later a second male appeared from behind a leaf and they immediately began to wrestle. They flipped one another repeatedly, interspersed with calls. Rather evenly matched, this went on for almost 15 minutes. Finally the victor held his ground, whilst the vanquished retreated from the hallowed ground.

 

Upon reviewing the photos and videos, I felt privileged to have witnessed such a behaviour from a vanishing species. This is perhaps even truer than I'd originally thought, the two males despite their verisimilitude actually appear to be different species/sub-species. While one has all the characteristics befitting O. lehmanni, the other whose white fingertips, slightly broadened head and differing banding patterns indicates some degree of hybridization with the very closely related Oophaga histrionica. Perhaps extinction will not come in the form of habitat loss or extinction (though harbour no illusions that this undoubtedly plays its role), but through hybridization, and its absorption into a larger more robust population. To purists and hobbyists this would still represent a tragedy, though perhaps it's a gentler swan song, a muting of a call rather than its abrupt silencing.

This large fresco of an epic battle is by Giuseppe Cesari, aka Cavalier d'Arpino (circa End 16th/Beginning 17th Centuries).

 

The painting depicts the Romans under Tullus Hostilius, third king of Rome, in violent battle against two neighbouring Etruscan cities. It was part of the wars that led to the absorption of Etruria into Rome.

Early morning free-fall sun absorption

The Attire of the Rovingian Nomadic Monks - Tradition, Inspiration, and Functionality - Part II by Daniel Arrhakis (2026)

 

® All designs created by Daniel Arrhakis.

  

4. Design Variations and Customization

 

Rovingianism is not a rigid monastic order, but a spiritual path based on individual freedom and personal journey. Therefore, the habit does not function as a fixed uniform: it evolves with the monk's journey, the climates he traverses, the available materials, and the symbols he chooses to incorporate.

 

Variations according to route and climate

 

Nomads of the cold highlands: use dense wools, handcrafted felt, heavy linens, and lanolin-rich fabrics, capable of protecting against wind, rain, fog, and altitude.

 

Dense wools for thermal insulation.

 

Rustic fibers, such as burel or wild goat skin.

 

Leather reinforcements on the shoulders and elbows to resist the friction of backpacks.

 

Earthy tones: rocky grays, deep browns, and moss greens.

 

Forest and woodland nomads: favor heavy cotton, rustic hemp, and moisture-resistant fabrics, suitable for dense trails, branches, brambles, and damp soil.

 

Robust cotton to resist tearing.

 

Rustic hemp for durability and moisture resistance.

 

Camouflage tones, such as leaf green, moss, and bark brown.

 

Botanical dyeing with berries, bark, and leaves.

 

Waxed reinforcements on hems to reduce mud and dew absorption.

 

Desert nomads: use lightweight linens, raw cotton, and ample layers to promote air circulation and protect against sun, sand, and intense heat.

 

Flowing and breathable linens.

 

Raw cotton, capable of reflecting solar radiation.

 

Long cloaks and voluminous scarves against sandstorms.

 

Solar tones: white, sand, ochre, and deep indigo.

 

Local plant fibers for durable details.

 

Travel Patchwork: As the robe wears out, the monk patches it with found, exchanged, or inherited fabrics. These patches, inspired by techniques such as boro or sashiko, transform the garment into a visual record of the lands visited.

 

Personal Tones, Dyes, and Patterns

 

The color palette functions as a visual geography. Each shade reveals the monk's relationship with the environment and can be obtained through natural dyes.

 

Earth and Root Tones: Deep browns obtained from walnut shells, oak, or roots.

 

Greens and Lichens: Olive, moss, and grayish tones, associated with vegetation and spiritual camouflage.

 

Ash and Charcoal Grays: Used by monks connected to purification rituals by fire or to mountainous and volcanic areas.

 

Painted and Embroidered Patterns

 

The personalization of the robe is understood as a form of active meditation. The monk may paint, embroider, or engrave symbols that translate their relationship with nature and with the journey itself.

 

Animistic protection patterns: motifs inspired by leaves, watercourses, footprints, or sacred animals.

 

Travel lines: abstract bands and contours that evoke crossed rivers, climbed mountains, or traveled paths.

 

Sacred imperfection: asymmetries and irregularities are valued as an expression of change, wear, and acceptance.

 

The final garment thus becomes a living logbook: dark, patched garments suggest long journeys through cold mountains, while plant patterns painted on green linen may reveal a recent experience in fertile valleys.

 

5. Pseudo-writing Patterns

 

Pseudo-writing patterns are one of the most mysterious elements of Rovingian attire. They do not correspond to a fixed alphabet or a functional script; rather, they serve a spiritual, aesthetic, and meditative purpose.

 

Since Rovingianism values individual freedom, these characters represent an intuitive language: an attempt to visually translate sounds of nature, meditation visions, the flow of wind, or the movement of water.

 

Types of Pseudo-writing

 

1. Types of Rovingian Pseudo-writing

 

Organic glyphs: inspired by branches, cracks in ice, erosion marks, or mountain contours.

 

Flowing cursive writing: continuous and interwoven lines, painted in a single gesture, evoking wind, water, or movement.

 

Abstract sacred geometry: dots, parallel lines, and concentric circles suggesting star maps, lunar cycles, or seasons.

 

Application methods

 

Hand painting: application of natural pigments made from charcoal, clay, berries, or minerals.

 

Subtle embroidery: characters embroidered on threads slightly different from the fabric, creating relief and textile reinforcement.

 

Woodblock printing: patterns stamped with seals carved by the monk himself.

 

Spiritual Purpose

 

Active Meditation: Drawing or embroidering without literal meaning helps focus the mind on gesture and rhythm.

 

Traveler's Secret: Because it is not legible to others, the pseudo-writing preserves the monk's spiritual intimacy.

 

Mystical Camouflage: From a distance, the patterns break the human silhouette and blend the body with natural textures.

 

6. The Double Hood

 

The double hood that appears on some costumes, is one of the most ingenious and striking features of the garment. The overlapping of two layers responds to the need for climate adaptation, meditative isolation, and protection in various demanding natural environments.

 

Inner hood: spiritual and contact layer

 

Material: soft and breathable fabrics, such as washed linen, rustic cotton, or fine wool.

 

Practical function: retains body heat and protects the ears from the wind without completely blocking hearing.

 

Spiritual function: limits peripheral vision during walking meditation, creating a space for inner concentration.

 

Outer hood: protective and environmental layer

 

Material: waxed thick linens, beaten wool, or fabrics treated with natural oils.

 

Practical function: protects against heavy rain, snow, wind, and intense sun.

 

Visual function: the depth of the hood casts a shadow over the face and breaks up the silhouette of the head in the natural environment.

 

Dynamics of use while traveling

 

The main advantage of the double hood is its modular versatility, allowing for different configurations according to the climate, social context, or the meditative state of the monk.

 

In mild weather or camping: the outer hood can be lowered, keeping only the inner layer.

 

During a storm: both hoods are raised; the outer hood deflects water and wind, while the inner hood retains heat.

 

In deep meditation: the inner hood reduces visual stimuli, and the outer hood creates a zone of personal retreat.

 

In the final silhouette, the double hood adds volume, mystery, and presence to the shoulders and neck. Combined with wide-legged trousers and a wrap-around tunic, it creates an imposing, functional, and timeless figure.

  

7. The Cloth Belt or Sash

 

In the tradition of Rovingian nomadic monks, the cloth belt represents the continuous flow of vital energy and spiritual discipline. Similar to the obi (sash) used in a martial arts kimono, this belt is long and wraps around the waist several times. It may also contain ritualistic natural elements hanging from cords.

 

The Symbolism of Colors

 

In Rovingianism, the choice of belt color is a purely personal and contextual expression, not a system of ranking or power. The absence of a rigid hierarchy reinforces the nomadic philosophy that each spiritual journey is unique and self-directed.

 

Factors Determining Color

 

Environment: The color adapts to the geography (e.g., earth tones for forests or white for snow), promoting camouflage and harmony with the environment.

 

Individual Path: Reflects the monk's current life stage, internal challenges overcome, or current spiritual vow.

 

Personal and spiritual symbolism. The meaning of each color is defined by the wearer, making the belt a mirror of their consciousness.

4. Variações de Design e Personalização

 

O Rovingianismo não é uma ordem monástica rígida, mas um caminho espiritual assente na liberdade individual e na jornada pessoal. Por isso, o traje não funciona como uniforme fixo: evolui com o percurso do monge, com os climas que atravessa, os materiais disponíveis e os símbolos que decide incorporar.

 

Variações conforme a rota e o clima

 

Nómadas das terras altas e frias: utilizam lãs densas, feltro artesanal, linhos pesados e tecidos ricos em lanolina, capazes de proteger contra vento, chuva, nevoeiro e altitude.

 

Lãs densas para isolamento térmico.

 

Fibras rústicas, como burel ou pelo de cabra selvagem.

 

Reforços em cabedal nos ombros e cotovelos para resistir ao atrito das mochilas.

 

Tons telúricos: cinzentos rochosos, castanhos profundos e verdes musgo.

 

Nómadas das florestas e bosques: privilegiam algodão pesado, cânhamo rústico e tecidos resistentes à humidade, adequados a trilhos densos, ramos, silvas e solos húmidos.

 

Algodão robusto para resistir ao rasgo.

 

Cânhamo rústico pela durabilidade e resistência à humidade.

 

Tons de camuflagem, como verde-folha, musgo e castanho-casca.

 

Tingimento botânico com bagas, cascas e folhas.

 

Reforços encerados nas bainhas para reduzir a absorção de lama e orvalho.

 

Nómadas do deserto: recorrem a linhos leves, algodão cru e camadas amplas para favorecer a circulação do ar e proteger contra sol, areia e calor intenso.

 

Linhos fluidos e respiráveis.

 

Algodão cru, capaz de refletir a radiação solar.

 

Mantos longos e lenços volumosos contra tempestades de areia.

 

Tons solares: branco, areia, ocre e índigo profundo.

 

Fibras vegetais locais para detalhes resistentes.

 

Retalhos de viagem: à medida que o traje se desgasta, o monge remenda-o com tecidos encontrados, trocados ou herdados. Estes remendos, inspirados em técnicas como boro ou sashiko, transformam a roupa num registo visual das terras visitadas.

 

Tons, tinturas e padrões pessoais

 

A paleta de cores funciona como uma geografia visual. Cada tom revela a relação do monge com o ambiente e pode ser obtido através de tinturas naturais.

 

Tons de terra e raízes: castanhos profundos obtidos de cascas de noz, carvalho ou raízes.

 

Verdes e líquenes: tons oliva, musgo e acinzentados, associados à vegetação e à camuflagem espiritual.

 

Cinzentos de cinza e carvão: usados por monges ligados a rituais de purificação pelo fogo ou a zonas montanhosas e vulcânicas.

 

Padrões pintados e bordados

 

A personalização do traje é entendida como uma forma de meditação ativa. O monge pode pintar, bordar ou gravar símbolos que traduzem a sua relação com a natureza e com a própria jornada.

 

Padrões de proteção animista: motivos inspirados em folhas, cursos de água, pegadas ou animais sagrados.

 

Linhas de viagem: faixas e contornos abstratos que evocam rios cruzados, montanhas superadas ou caminhos percorridos.

 

Imperfeição sagrada: assimetrias e irregularidades são valorizadas como expressão de mudança, desgaste e aceitação.

 

O traje final torna-se, assim, um diário de bordo vivo: vestes escuras e remendadas sugerem longas passagens por montanhas frias, enquanto padrões vegetais pintados sobre linho verde podem revelar uma vivência recente em vales férteis.

 

5. Padrões de Pseudoescrita

 

Os padrões de pseudoescrita são um dos elementos mais misteriosos do traje rovingiano. Não correspondem a um alfabeto fixo nem a uma escrita funcional; cumprem antes um propósito espiritual, estético e meditativo.

 

Como o Rovingianismo valoriza a liberdade individual, estes caracteres representam uma linguagem intuitiva: uma tentativa de traduzir visualmente sons da natureza, visões de meditação, o fluxo do vento ou o movimento da água.

 

Tipos de pseudoescrita

 

1. Tipos de Pseudoescrita Rovingiana

 

Glifos orgânicos: inspirados em ramos, fendas no gelo, marcas de erosão ou contornos de montanhas.

 

Escrita cursiva de fluxo: linhas contínuas e entrelaçadas, pintadas num único gesto, evocando vento, água ou movimento.

 

Geometria sagrada abstrata: pontos, linhas paralelas e círculos concêntricos que sugerem mapas estelares, ciclos lunares ou estações.

 

Métodos de aplicação

 

Pintura manual: aplicação de pigmentos naturais feitos de carvão, argila, bagas ou minerais.

 

Bordado subtil: caracteres bordados em fios ligeiramente diferentes do tecido, criando relevo e reforço têxtil.

 

Impressão por bloco de madeira: padrões carimbados com selos esculpidos pelo próprio monge.

 

Propósito espiritual

 

Meditação ativa: desenhar ou bordar sem significado literal ajuda a focar a mente no gesto e no ritmo.

 

Segredo do viajante: por não ser legível para outros, a pseudoescrita preserva a intimidade espiritual do monge.

 

Camuflagem mística: à distância, os padrões quebram a silhueta humana e misturam o corpo com texturas naturais.

 

6. O Duplo Capuz

 

O duplo capuz que surge em alguns trajes, é uma das características mais engenhosas e marcantes do traje. A sobreposição de duas camadas responde à necessidade de adaptação climática, isolamento meditativo e proteção em ambientes naturais exigentes.

 

Capuz interior: camada espiritual e de contacto

 

Material: tecidos macios e respiráveis, como linho lavado, algodão rústico ou lã fina.

 

Função prática: retém calor corporal e protege as orelhas do vento sem bloquear totalmente a audição.

 

Função espiritual: limita a visão periférica durante a meditação em caminhada, criando um espaço de concentração interior.

 

Capuz exterior: camada de proteção e ambiente

 

Material: linhos grossos encerados, lã batida ou tecidos tratados com óleos naturais.

 

Função prática: protege contra chuva forte, neve, vento e sol intenso.

 

Função visual: a profundidade do capuz projeta sombra sobre o rosto e quebra a silhueta da cabeça no ambiente natural.

 

Dinâmica de uso na viagem

 

A principal vantagem do duplo capuz é a sua versatilidade modular, permitindo diferentes configurações conforme o clima, o contexto social ou o estado meditativo do monge.

 

Em tempo ameno ou no acampamento: o capuz exterior pode ser baixado, mantendo apenas a camada interior.

 

Sob tempestade: ambos os capuzes são erguidos; o exterior desvia água e vento, enquanto o interior conserva calor.

 

Em meditação profunda: o capuz interior reduz estímulos visuais, e o exterior cria uma zona de recolhimento pessoal.

 

Na silhueta final, o duplo capuz acrescenta volume, mistério e presença aos ombros e ao pescoço. Em conjunto com as calças largas e a túnica cruzada, cria uma figura imponente, funcional e intemporal.

  

7. A Faixa ou Cinto de Pano

 

Na tradição dos monges nômades rovingianos, o cinto de pano representa o fluxo contínuo de energia vital e a disciplina espiritual. Semelhante ao obi (faixa) utilizado num Quimono de Artes Marciais, este cinto tem um formato longo e envolve a cintura várias vezes. Pode conter igualmente elementos naturais ritualísticos pendurados por cordões.

 

O Simbolismo das Cores

 

No Rovingianismo, a escolha da cor do cinto é uma expressão puramente pessoal e contextual, e não um sistema de graduação ou poder. A ausência de uma hierarquia rígida reforça a filosofia nômade de que cada jornada espiritual é única e autodirigida.

 

Fatores que Determinam a Cor

 

Ambiente: A cor adapta-se à geografia (ex: tons de terra para florestas ou branco para a neve), promovendo a camuflagem e a harmonia com o meio envolvente.

 

Percurso Individual: Reflete o momento de vida, os desafios internos superados ou o voto espiritual atual do monge.

 

Simbolismo pessoal e espiritual. : O significado de cada cor é definido pelo próprio portador, tornando o cinto um espelho da sua consciência.

This experiment was an attempt to recreate the fluorescence of chromium activated corundum (aka 'ruby'). Aluminum hydroxide was mixed with 1-4 drops of Cr(III) oxide in a basic solution. This was placed on a small amount of aluminum sulfate in an aluminum foil container and a bit of water was added.

 

The sample was then heated, first with a propane torch until the water was removed and then with a MAPP gas torch until the aluminum sulfate expanded into foam, trapping the aluminum hydroxide which was calcined into aluminum oxide by the torch's flame. (at least that was the plan)

When we visited the current GOMA art works which profiles art by Australian artists, we were totally in awe of an animated work by Deborah Kelly - Beastliness.

 

These two girls were similarly affected, and the moment needed capturing.

 

This work is described as:-

The second work, Beastliness 2011, is a fast-paced animation. Taking aesthetic cues from MTV as well as early twentieth-century collage, Kelly’s characters are uncanny fusions of animals, insects and women in a world of frenzied dancing. Kelly re-mythologises femininity, avoiding the stereotypes that constrain and demonise people for their difference.

 

Kelly’s strategy is to embrace diversity: these creatures represent many female forms, thoughts and experiences, and celebrate acceptance and freedom of expression.

 

I tried to figure out how to use the Canon 60D movie mode, but couldn't find it in the dimmed lighting. I know it is there, just needed to find the beast.

(Looked just now and found the movie mode button which has obviously been installed on my camera since Saturday while I was sleeping)

 

I am sure these girls had a story to tell later over coffee about what they interpreted from the display.

 

Speaking of movies, look at this music video with a DIFFERENCE

My favorite Ansel Adams photograph is "Clearing Winter Storm," and so I was desperately hoping for a storm when I visited Yosemite (even though I knew I'd never get a photo as good as Ansel's as I'm not that talented!). Luckily, on the third day, this storm rolled in and brought a ton of fog with it. The fog was pouring down El Capitan like waterfalls and spiraling through the trees on the valley floor. The view was so amazing I shot five rolls of film of the changing views, plus a few shots with the digital camera for some instant gratification. This is one of the digital shots; the film shots will be scanned over the next couple of days as there are a TON of rolls of film from the trip and developing and scanning them takes awhile...

Day 177 (v 9.0) - sucked in again

In the summer of 2021, I had J-131, a radioactive iodine isotope with a half-life of eight days in my body. For the duration of its absorption by the body, or more precisely, the targeted destruction of parts of it and the excretion of the material by it, I was in radiation quarantine. Such, I had enough time to capture this for me probably unique moment of being in direct contact with radioactivity. Visualising this invisible phenomenon fascinated me. The result is a limited series of Polaroids that visualise the half-life and radiation of the material in the intensity of the respective results. I did not take photographs or paint with light (deriving from the greek wtó, Ypáeiv (photós graphein), photography initially means “light” and “to paint/write/draw” and refers to both the process and the result). I only shot with body fluids.

  

(this is a photograph with my mobile during an exhibition with a reflection of myself in the framed work)

"Date: 2019. Artist: Ulrike Koch-Brinkmann. Medium: Marble stucco on plaster cast, natural pigments in egg tempera, gold foil.

 

The statue type known as Small Herculaneum Woman has survived in dozens of ancient marble replicas. This reconstruction is based on studies of the extensive color preserved on a replica found in Delos, which has been examined in ultraviolet, infrared, and raking light as well as with X-ray fluorescence spectroscopy and ultraviolet-visible absorption spectroscopy. Decorative elements on the undergarment were painted with a light Egyptian blue, and iron-based pigments in shades of red and brown were used for the hair and facial features. Green malachite survived in large areas of her mantle, blackened through fire.

 

"The Late Classical prototype of the so-called Small Herculaneum Woman is lost, but dozens of copies of the Hellenistic and Roman periods are preserved. The young woman, her hair composed of several strands woven together into a severe bun, wraps herself in a mantle that she draws tightly around her body with both hands. Beneath the mantle she wears a finely pleated undergarment and sandals with thick soles. The reconstruction was made in 2019, as part of a project financed by the Federal Ministry for Education and Research, "The university collection as living archive. Teaching and research at the intersection of materiality and communication." It is based on studies of the polychromy of a copy found in 1894 on Delos (National Archaeological Museum, Athens, inv. 1827). The cast was taken from the Roman copy that gives the statue type its nickname, discovered in 1706 in Herculaneum (Staatliche Kunstsammlungen Dresden inv. Hm 327).

 

The polychromy of the copy from Delos has been investigated on several occasions since 1982. The best-preserved colors are a light blue (Egyptian blue) for decorative elements of the under-garment and a whole palette of iron oxides in shades of red and brown, especially on the hair and face. The excavators at the end of the 19th century had already observed traces of a rich pink and violet. Traces of gilding and of a violet color, the result of corrosion, are preserved on the borders of the mantle.

 

Yellow pigment containing lead, as well as lead white and malachite that had been burned to a grey-black powder, could also be detected with the use of intensive scientific investigation. In ultraviolet light, bands of wave and ray patterns can be seen on the mantle. The reconstruction brings together all the colors that have been detected since the statue was excavated. The application of paint on the mantle makes especially clear what the sculptor's intentions were: the fine, greenish fabric is transparent wherever the garment is pulled tightly around the body. Thus, the flesh color of the arm and elbow, as well as the violet of the undergarment, shines through at the belly and right thigh.

 

The decoration of the dress hem with sea monsters and the pomegranate branch on the mantle hem are designed in analogy to robe depictions in vase painting of the 4th century BC and on Hellenistic sculpture."" - info from the Met.

The absorption of Robson’s into the United Glass Group in 1980 saw a strong phase of buying Scanias, a marque favoured by the United Group. A121 JLS Border Rebel was the first three-axle tractor unit in the Robson’s fleet. This tag-axle 6x2 was used on short-haul tipper work carrying ten loads a day of specialist silica sand used for glass-making. It may have been fitted with a day cab rather than the sleeper version depicted here (25-Oct-18).

Although carrying its Greater Manchester Transport legal lettering following the absorption of the Lancashire United fleet just under two months earlier, not a great deal else had changed by the time of this May 1981 shot of ex-LUT Leyland Fleetline / NCME 497, having just set out on the long run from Manchester to Liverpool. It had still to be renumbered 6913 in the GMT series and its eventual repaint might have also been some way off.

 

This was one of a pair from this batch that saw further service with Chesterfield Transport after their sale by GM Buses.

The gradual absorption of Germanwings into a growing Eurowings continues with pace, and whilst the airline operates a subsidiary of the larger low-cost unit with their own flight number and crews, that is soon coming to an end as a number of Germanwings Airbus A319/A320's are in the process of being repainted into Eurowings colours.

Another transition is the ending of Germanwings abandoning its 4U IATA flight codes and going over the Eurowings EW code from 25th March 2018. With Eurowings growing, Germanwings is now becoming a more redundant brand, and with the amount of planes Eurowings intends to repaint, it is likely they will be gone by 2018.

The first 2 Airbus A319's from Germanwings have already transferred over to Eurowings Europe in Vienna. Meanwhile at Eurowings, 2 Airbus A319's have since transferred with another 3 expected to join the fleet, whilst one older Airbus A320 is also expected to join the fleet.

Currently, Germanwings operates 48 Airbus A320 family aircraft, which includes 36 Airbus A319's and 12 Airbus A320's (4 currently in storage).

Alpha Golf Whiskey Alpha is no longer in service with Germanwings, delivered new to the low-cost carrier in July 2006 initially on lease from SAAM and now SMBC since July 2013. She is currently at Norwich since October 2017 being repainted into Eurowings colours. She is powered by 2 International AeroEngines IAE V2524-A5 engines.

As early as 1762, art historian Johann Joachim Winckelmann used the well-preserved colors on the statue of Artemis from Pompeii as evidence that ancient marble sculpture was colorful. The wide range of pigments represented on the reconstruction was identified through ultraviolet-visible absorption spectroscopy, ultraviolet-induced visible luminescence, and visible-induced infrared luminescence. These include Egyptian blue; pink madder; kaolin mixed with lead white; orange and red ocher; hematite; cinnabar; umber; and two yellow pigments made from lead and ocher." - info from the Met.

This photo is really just meant to be informative and educational for those that are curious about the Universe, and want to know how things work. As photographers we capture Photons after all, so here is a bit of the Physics behind the light that we love to capture.

 

This image shows the Electromagnetic Spectrum of light from the Sun, after traveling through Earth's blue Nitrogen rich skies (photographed through a Quantitative Spectroscope).

 

The nanometer scale in the Spectroscope shows the wavelengths of visible light, that range from 400 nm - 700 nm. Invisible light at shorter wavelengths (beyond violet) include Ultraviolet (UV), X-Ray and Gamma Ray. Longer wavelengths of light (beneath red) include Infrared, Microwave and Radio Waves.

 

About the Sun:

The Sun is a G-type Main-Sequence Yellow Dwarf (G2V) Star. Through the process of fusion, the Sun burns approximately 600 million tonnes (metric tons) of Hydrogen each second, turning it into 596 million tonnes of Helium. As the Hydrogen nuclei fuse, Photons are emitted, which in short is why the Sun shines (and all the other stars). The Hydrogen Atom is the simplest and most abundant element in the Universe (with only 1 Proton and 1 Electron).

 

Through the process of fusion, more complex elements are made at different stages of a star's life and death cycle. This is what Carl Sagan meant with one of his well known quotes from Cosmos, “The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.”

 

The Sun is roughly 150,000,000 km from Earth. The speed of light is 300,000 km/sec (186,000 miles/sec), which means that the light took just over 8 light-minutes (8 minutes and 26 seconds) to reach the Spectroscope in front of my camera lens.

 

Here is a very simplistic explanation of Spectroscopy, and how the Electromagnetic Light Spectrum is used in Astrophysics:

This image was photographed through a basic "High School Science Classroom" Quantitative Spectrometer (100 line resolution). With higher resolution Spectrometers on Telescopes, Astronomers can determine what chemical elements Stars and Planets are made of, as each chemical element has a unique light absorption fingerprint, that shows up as dark lines in the spectrum.

 

The amount that the absorption lines are shifted to red or blue (redshift and blueshift), is due to the Doppler effect and gives an indication if the celestial object is moving towards or away from us, and at what speed. This is how Scientists and Physicists know what the observable Universe is made of, and that the Universe is expanding.

Planets, stars, nebulas and a galaxy -- this impressive image has them all. Closest to home are the two planets Mars (right) and Saturn (center), visible as the two bright orange spots in the upper half of the featured image. On the central right are the colorful Rho Ophiuchus star clouds featuring the bright orange star Antares lined up below Mars. These interstellar clouds contain both red emission nebulas and blue reflection nebulas. At the top right of the image is the Blue Horsehead reflection nebula. On the lower left are many dark absorption nebulas that extend from the central band of our Milky Way Galaxy. The featured deep composite was composed of multiple deep exposures taken last month from Brazil. Although you need a telescope to see the nebulosities, Saturn and Mars will remain visible to the unaided eye this month toward the east, just after sunset. via NASA ift.tt/1Xj749i

The Horsehead, also known as Barnard 33, is a cold, dark cloud of gas and dust, silhouetted against the bright nebula, IC 434. The bright area at the top left edge is a young star still embedded in its nursery of gas and dust. But radiation from this hot star is eroding the stellar nursery. The top of the nebula also is being sculpted by radiation from a massive star located out of Hubble's field of view.

 

Only by chance does the nebula roughly resemble the head of a horse. Its unusual shape was first discovered on a photographic plate in the late 1800s. Located in the constellation Orion, the Horsehead is a cousin of the famous pillars of dust and gas known as the Eagle nebula. Both tower-like nebulas are cocoons of young stars.

The phenomenon of the Green Ray (or Flash) occasionally seen at sunset or — with greater difficulty — at sunrise is beautifully described by Marcel Minnaert In his book: "The nature of Light and Colour in the open air" (Dover publications inc., New York, 1954, pp. 58–63). As I have reported in a previous post ( www.flickr.com/photos/bob_81667/40402297274/ ), the visibility of the phenomenon is dependent on scattering and absorption processes occurring during the long path that sunlight takes through Earth's atmosphere to reach our eyes at these times. These processes result in what is known as the telluric spectrum of the sun which is distinct from the absorption resulting from the escape of light through the solar atmosphere.

 

The telluric spectrum of the sky and of the sun itself varies during the day (and night) depending on both the altitude of the sun above the horizon and on the varying content of atmospheric gases, most notably that of water vapour. In his book, Minnaert shows a rough sketch of the visual spectrum of the setting sun seen through a visual spectroscope (Fig. 55, credited to N. Dijkwel, Hemel en Dampkring, 34, 261, 1936). This shows the development of the gap between the green and the red segments of the spectrum as the sun reaches the horizon but is attributed by him to water vapour absorption which, although it does play a minor role, the much larger effect of ozone absorption on the spectrum of twilight was not widely appreciated at that time.

 

In this picture, I assemble some of the historical drawings along with modern digital spectra to help give a clearer picture of the contributors to the sunset spectrum.

 

The lower frame in the picture is the sketch from Minnaert's book of the of the sunset spectrum developing downwards with time. I assume that this is a prismatic spectrum which is squashed up towards the red end compared with the linear grating spectrum in the upper plot. I have coloured Minnaert's picture to show the correct orange colour between the middle two absorption bands. The 4th strip from the top shows two pairs of absorption bands that I have labelled, from the right to left, A, B, R and Greek(delta).

 

[Note added in December 2020: I am not certain in my attribution of the of the two reddest absorptions in row 4 to Fraunhofer A and B as was suggested by their position in the drawing. My own examinations of the setting sun with a visual prism spectroscope reveal that the two bands, alpha near 630nm and the combination of Fraunhofer C (H-alpha) and the water band near 650nm form a more prominent pair. If this is the case, it is worth remarking that these four features drawn in row 4 contain two bands from tetra-oxygen that could not be identified as such at the time of the original investigations by Ångström and others in the 19th century. It is now known that such CIA (see below) transitions contribute a small but significant part of the ensemble of absorptions that produce the global greenhouse effect. I think that the fact that we can see these bands with the eye through a simple spectroscope is interesting.

 

I have now (10/12/2020) replaced the figure with this new, and more likely, interpretation of Dijkwel's drawing.]

 

Above this, I have reproduced (in mirror image to reverse the spectral direction) the observations of the telluric spectrum made by Ångström and shown in the book "Spectrum Analysis" by H. Schellen, D Appleton and Company, New York, 1872, Fig. 95, p183. This is on a linear wavelength scale aligned with the spectral plots at the top of the picture. Download the full size version of the image to read the labelling on this. The drawing shows the strong solar Fraunhofer lines as well as the telluric features. Note that it also includes the blue tetra-oxygen feature at ~476nm that was shown at a shorter wavelength in one of Ångström and Thalén's (presumably earlier) maps shown in plate VI of the above book.

 

The top plot shows a sunset spectrum (blue line) and also a spectrum of the eclipsed moon (Pallé, E. et al. Nature volume 459, pages 814–816 (11 June 2009) — red line). These are marked with the major telluric lines and bands from H_2 O (water), O_2 (molecular oxygen), O_3 (ozone) and the O_2 * O_2 dimer (now known as the CIA O_4 Collisionally Induced Absorption). Overlayed on this is the first reported spectral plot I have found of the central part of the ozone Chappuis band absorption and reported in the Astrophysical Journal in 1934 ( articles.adsabs.harvard.edu/cgi-bin/nph-iarticle_query?19... ). This is inverted and flipped left-right but you can see the characteristic double dip at the centre of the Chappuis band. The red and blue line spectra are plotted as a ratio of the the spectrum of an uneclipsed moon (top) and the spectrum of the sun seen high in the sky (bottom, blue line). This results in the removal of the intrinsic spectrum of the sun, leaving only the telluric spectrum.

 

So what's going on here? The principal difference between the red and blue line spectra (eclipse and sunset) in the top plot is the path that the sunlight takes through the atmosphere in these two situations. In the lunar eclipse, the light grazes the Earth on its way to producing the 'copper-coloured' moon but, in this case, the path avoids the low altitude atmosphere where most of the water vapour resides. You can see that the water band absorptions are much weaker than in the blue sunset spectrum. The other difference — a more subtle one — is that the CIA features (notice especially the one around 578nm) are stronger in the sunset spectrum which was obtained from a low altitude observing site, essentially sea-level. This is because the formation of the CIA lines needs two adjacent oxygen molecules and so its strength is dependent on the oxygen partial pressure squared and so is only really produced in the low atmosphere.

 

How do we interpret the spectrum sketches in Minnaert's book? The clear separation between the green and red segments in the 5th strip down is predominantly due to the ozone Chappuis absorption (see the model spectra in: www.flickr.com/photos/bob_81667/40402297274/ ). The central pair of absorptions seen in the 4 strips above is partly the result of the shape of the central part if the ozone Chappuis band but it is enhanced by the CIA absorption on the short wavelength side and by the water absorption on the long wavelength side. This water band was known by Victorian observers as "The Rain Band" since is was supposed to appear more strongly in damp weather and so was used for forecasting rain (though not very successfully!) This spectral region has a very characteristic appearance in a visual spectroscope with what appears to be a broad yellow 'emission' band flanked on either side by significant absorption. It is strong in both the sky and solar spectra when the sun is low: I have labelled these absorptions by 'delta' (as used by Ångström) and 'R' for Rainband. These are shown very clearly in the Spectral drawings by Piazzi Smyth made in 1875/6.

See: www.flickr.com/photos/bob_81667/11433988063/

 

The absorptions further to the red in the Minnaert sketch I suggest should be identified with the very strong molecular oxygen bands known as Fraunhofer 'A' and 'B' although it is not obvious why only a single band is shown on the 3rd strip. Maybe the observation was influenced by a strong water band marked 'a'?

 

Why should we be so interested in this apparently rather arcane branch of observational astronomy, even though it was all-the-rage in the late 19th century? The reason is that the use of long light paths through planetary atmospheres that can be extracted from observations of a planetary transit (when the planet crosses the disc of its ‘sun’) is one of the primary ways of learning about exoplanet atmospheres, currently a major ‘industry’ in astrophysics.

I found this man lying on the sidewalk when i walked out my door yesterday. He was totally out of it, would barely respond to anything let alone say something coherent. He was so drunk he had soiled himself and he was lying across the sidewalk without any form of shelter.

I called for an ambulance but they sent the police, who proceeded to "wake" him up before taking him to the station. I hope he had a good night sleep in a holding cell, it was storming and raining yesterday so it was probably better than staying on our sidewalk..

"Date: 2010. Artist: Ulrike Koch-Brinkmann. Medium: Polymethyl metacrylate.

 

"This richly decorated statue stood on the tomb of a girl named Phrasikleia. She wears a crown of lotus buds and holds a single bud in her left hand. The epigram on the base tells us that she died young, before she could marry.

 

The famous sculptor Aristion of Paros signed the work. With the help of ultraviolet-visible absorption spectroscopy (UV-Vis spectroscopy) and X-ray fluorescence spectroscopy (XRF), traces of a numbers of colors on the flesh and clothing could be identified: red and brown madder, red and brown ocher, lead white for the eyes, flesh, and hair, as well as three different reds and yellows (red and yellow iron oxide and orpiment for the garment). Wherever the underside of the fabric is visible - on the sleeve and the lower hem - a dark red pigment (hematite) was deliberately used. Gold leaf and lead tin foil that gleams like silver were applied to the dress and the jewelry.

 

Metal rosettes and shiny yellow swastikas (painted with orpiment and gold ocher) were scattered over the entire garment. Additionally, stars appear on the back of the garment, evidently intended to represent a constellation.

 

The reconstruction made in 2010 follows the incised patterns and colors that were identified by scientific analysis. But after the latest discoveries by the conservators in the Athens National Museum, the red ocher of the robe has been mixed with cinnabar, giving the color an even more intense effect. The polish of the skin was based on contemporary Egyptian mummy portraits and was

 

done using agate, while a shimmering lacquer (gum arabic) was applied to the irises of the eyes. In 2019, gilding was added to the volute ornament of the belt and precious stones were inserted into the round depressions that are still preserved."" - info from the Met.

The fall of 2022 I did my 3rd major cycling tour. I began my adventure in Montreal, Canada and finished in Savannah, GA. This tour took me through the oldest parts of Quebec and the 13 original US states. During this adventure I cycled 7,126 km over the course of 2.5 months and took more than 68,000 photos. As with my previous tours, a major focus was to photograph historic architecture.
