A very distant spoonbill was momentarily the only creature stirring to life as the sun just peeped over the horizon and lit up the underside of the low cloud with a wonderful red glow.
Taken at Mannum on the Murray river in South Australia.
Panoramic view from Lily Point lookout,Point Roberts Washington.On the left are Mt Spickard and Mox Peaks,in the middle there's too many peaks to name them all includes Whatcom Peak,Indian and red Face mountain and Mineral Mountain.Then mid right is Mt Baker and then South Twin,North Twin and Kulshan.On the left ,the south part of White Rock,BC,Canada.In the middle ,Blaine,Washington,USA.
Vue panoramique depuis le belvédère de Lily Point, Point Roberts Washington. Sur la gauche se trouvent les monts Spickard et Mox Peaks. Au milieu, il y a trop de sommets pour les nommer tous, notamment Whatcom Peak, Indian and Red Face Mountain et Mineral Mountain. Puis au milieu à droite se trouve le mont Baker puis South Twin, North Twin et Kulshan. À gauche, la partie sud de White Rock, BC, Canada. Au milieu, Blaine, Washington, États-Unis.
It's rare to have a sprite and a well-shaped halo (red disk next to the sprite) in such a distance (they were possibly triggered by separate electrical discharges), on Feb. 12-13, 2024, over thunderstorms at the Aegean Sea. Halos occur due to the same mechanism responsible for sprites, appear higher than them, at 70–85 km, last for some ms, and look like faint red disks with a typical diameter of less than 100 km. Also, observe the lower right tendrils of the sprite and their deviation towards the right, following the strong temporary electric field above the thundercloud.
TLEs (like red sprites) are upper atmospheric electrical discharges and they appear, under specific circumstances, above thunderstorms (e.g. red sprites appear at altitudes of 40-90 km).
I've used a #Sigma 85 mm lens at f/1.4, for 1/25'' with 40 k iso.

Some mornings, mother nature creates art!
A Riverland sunrise on the Murray river at Mannum, South Australia.
Atardecer en el valle del Jarama con la sierra de Guadarrama al fondo. Último días de un estio largo y que seguramente se extenderá más en el tiempo, aunuqe la estación cambie de nombre
Ceci n'est pas un coucher de soleil.....mais le rougeoiement du ciel nocturne éclairé par le lac de lave au fond du cratère du volcan Benbow.
Les lacs de lave bouillonnants des cratères du Benbow et du Marum, tous deux sur l'île d'Ambrym au Vanuatu,
ont malheureusement disparu depuis le 16 décembre 2018.
--------------------
This is not a sunset. It's the lava lake inside the crater off the volcan Benbow in Ambrym (Vanuatu) that illuminates the sky.
The bubbling lava lakes of Benbow and Marum craters, both on Ambrym Island in Vanuatu, have unfortunately disappeared since December 16, 2018.

Esta no es una puesta de sol ..... sino el resplandor del cielo nocturno iluminado por el lago de lava en el fondo del cráter del volcán Benbow.
Los burbujeantes lagos de lava de los cráteres Benbow y Marum, ambos en la isla Ambrym en Vanuatu,
lamentablemente han desaparecido desde el 16 de diciembre de 2018.
I have a question for any experts out there. Anyone with knowledge of lightning and atmospherics, and also anyone with working knowledge of camera sensors.
I took these two shots yesterday, more in hope than anything, Being lucky enough to have the Sony RX10 that shoots at 24 frames per second, I pointed at the sky across the street and held the shutter for a second. I got lucky and managed these two shots. Not very exciting looking, being daylight lightning shots, but I am intrigued by the difference in the two shots. They are consecutive frames 1/24th of a second apart. Bolt 1 shows up the brightest, and actually shows the lightning in its ground to air phase and the bolt is only half completed. Lightning bolt 2 shows the completed bolt all the way to the cloud, but is fading in brightness. The bolt itself was very close with barely a second elapsing between flash and the window rattling thunderclap!
My puzzle is the first shot that shows a purple halo around the upward end of the lightning, and a corresponding colour shift across the image in the sky below the top of the lightning.
I'd love to know is this just an issue with the sensor and its response to a sudden intense flash, or is it atmospheric?
My guess is the sensor, but I'd love to hear other opinions or experiences.
These two shots are both cropped heavily from the left half of the wide angle image, hence the slight distortion in the vertical lines of the house.
A double lightning strike during a nocturnal thunderstorm, south of Attica, towards the southern Saronic gulf. On the right side, one can see the island of Aegina. Can you spot the Kelvin-Helmholtz clouds on the right side of the bolt? Night of Sep. 5, 2023, during the storm system named "Daniel" that flooded Thessaly (more than 1000 mm of rain in 3 days).

Ever looked out your window at sunset and thought, wow it was just getting dark a minute ago. Now there’s a strange yellow glow emanating from somewhere. Bingo! That was this night.
Raios crepusculares (mais comumente conhecidos como raios solares ou raios divinos), na ótica atmosférica, são raios de sol que parecem irradiar do ponto no céu onde o sol está localizado. Esses raios, que fluem através das lacunas nas nuvens (particularmente stratocumulus) ou entre outros objetos, são colunas de ar iluminado pelo sol, separadas por regiões sombreadas de nuvens escuras. Apesar de parecer convergir em um ponto, os raios são na verdade feixes de luz quase paralelos. Sua convergência aparente é um efeito de perspectiva, semelhante, por exemplo, ao modo como as linhas ferroviárias paralelas parecem convergir em um ponto na distância.
O nome vem de suas ocorrências frequentes durante as horas crepusculares (aquelas ao entardecer e ao anoitecer), quando os contrastes entre claro e escuro são os mais óbvios. Crepuscular vem da palavra latina "crepusculum", que significa crepúsculo.

More than 30 TLEs were observed during the early morning of Mar. 28, 2023 over thunderstorms extending from Lesvos isl. up to SW Black Sea. My observation spot was at E. Attica, Greece. This was another double event with big sprites and a halo (the relatively faint red disk on top right side from the sprites). Parent lightning flash seen below, behind the mountains of S. Evia isl.
TLEs (like red sprites) appear, under specific circumstances, above thunderstorms (e.g. red sprites appear at altitudes of 40-90 km).
I've used a Sigma 85 mm lens at f/1.4, for 1/25'' with 51.2k iso.

saw this interesting cloud that resembles side view of a monkey.
Took a few shots before it change form.

During the thunderstorm on the night of June 10, 2022, over central Evia isl., Greece, there were many CA (Cloud-to-Air) lightning. In one of them, it was possible to capture the corona discharge with its distinct blue/purple color. These purple filaments/streamers are created due to high values of the electric field (high enough to ionize air molecules, mostly nitrogen). In this image, I've done a "double zoom in" so one can easily observe this phenomenon. Sigma Art lens 20 mm (big frame), 85 mm (smaller frames), at f/1.4 and iso 20-40k.
