4/24/17 SDOT introduced a new adaptive traffic control system along Mercer Street between 3rd Ave W and I-5 which coordinates the operation of the traffic signals in and around the corridor to help vehicles move more efficiently. The system adapts to varying traffic conditions, such as congestion that may result from sports events, concerts or hour-to-hour traffic volume changes in the area.
The new system is called “SCOOT” which stands for Split Cycle Offset Optimization Technique. It is the first use of this type of adaptive signal system in the city.
“This new system will adjust signal timing based on traffic in and around Mercer in real time. We know Mercer is the busiest corridor in the city,” said SDOT Director Scott Kubly. “SCOOT will help reduce the traffic backups we’ve seen along Mercer and help keep people moving.”
he Air and Missile Defense Planning and Control System (AMDPCS) provides an automated command and control system to integrate air and missile defense planning and operations. Planning and operations functions include radar and weapon systems analysis and emplacement locations based on critical and defended asset lists/prioritization. It also supports intelligence preparation of the battlefield, using information collected by internal AMDPCS subsystems; joint collaboration support for the development of airspace control measures utilized throughout the theater of operations; and logistics management activities, to ensure timely ammunition resupply and reduce repair cycle times.
There are two configurations of AMDPCS (AMDPCS-A and AMDPCS-B), which are deployed with Air Defense Artillery (ADA) batteries, battalions, brigades and U.S. Army Air and Missile Defense Command (AAMDC). AMDPCS is the only system in the Army fleet to provide these capabilities.

The new Siemens Vectron generation is suitable for both passenger and freight transportation. In both domestic and cross-border service, these locomotives can run at top speeds of 160 km/h or even 200 km/h. The various power classes and voltage systems provide the basis for flexible and demand-oriented locomotive configuration. Country-specific train control systems can be conveniently replaced or complemented. The photo shows the Vectron AC variant during a test trip in Kiruna, Sweden, in February 2012.
The 25 kV 50 Hz Vectrons will replace existing Soviet-built locomotives dating from the 1970s on passenger and freight services on the 1 524 mm gauge network. The 19 m long locomotives weighing 90 tonnes will have a maximum speed of 200 km/h and the capability of hauling 2 000 tonne trains. Rated at 6·4 MW, they will be equipped for regenerative braking, produce less waste heat than previous locomotives, and be equipped with two diesel engines for 'last mile' operation on unelectrified industrial lines, at docks and in yards.

EC-135A Airborne Launch Control System (ALCS)
Top Speed - 610 miles per hour
Crew - 15+
Range - Intercontinental
Payload - No weaponry; 31,000 gallons of fuel
An Airborne "Finger on the Button"
Crammed with electronics, one of three ALCSs from Ellsworth Air Force Base sat ready for takeoff at all times between 1970 and 1991. If an attack on the United States disrupted ground-based launch control sites, this plane's crew - from 30,000 feet in the air - could send nuclear missiles rocketing around the globe. But it was never really a button; crews turned keys to launch the missiles.
Specialists on board could communicate up and down the chain of command, from the President to individual combat crews.
Pumping Fuel at 300 miles per hour
Before it was converted for missile launch, this plane served Ellsworth Air Force Base's B-52 bombers as a flying gas station. Tankers from the 28th Air Refueling Squadron met bombers in midair, connected through the tail boom, and filled the bomber's tanks.

As coastal artillery guns became larger, and their range increased, growing demands were placed on the fire control systems that targeted potential naval targets. By World War II the 16” guns of Battery Townsley and Battery Davis could fire a projectile 25 miles to sea. And there is a lot of sea out there at that range. To be effective the projectile would have to strike its target and that is where the artillery fire control system came into play.
Fire control systems basically sighted targets from multiple vantage points along the shore. The vantage points were connected by baselines of known relationship. The sighting direction from each fire control station was transmitted to a central fire control plotting room where the readings were fed into an analog computer, essentially adjustable arms on a large plotting table (see video). The coordinates of a target ship were updated at 20 second intervals to establish a ship trajectory, A projectile fired by the 16” guns was in the air for about 90 seconds so several intervals of plotting would occur while the load was in flight.
Coastal batteries with smaller weapons could use fire control stations that were relatively close to each other. However, the range of the 16” guns required fire control stations that were quite far apart. In the Bay Area these began down past Pacifica to the south and ranged all the way up to Wildcat in Pt. Reyes. The Hill 640 Military Reservation, located on coastal bluffs just south of Stinson Beach near the intersection of Panoramic Highway and Highway 1, had five fire control stations with each station associated with a different 16” gun installation. The site has fire control stations for completed batteries (Townsley and Davis) and unfinished batteries (129 and 243) plus a fifth fire control station of unknown association. It is interesting that while the fire control stations all belonged to the same era they have different designs. There must be a story behind this circumstance. It is also interesting that targeting information was not shared between the batteries.
Our visit found the fire control stations all grouped together above Highway 1. They seem to be in pretty good shape for structures built 70 years ago.

The attached shows a dense section of the summer Milky Way in the constellation of Sagittarius which contains, among other objects, the Lagoon, Trifid & IC 4685 nebulae (at bottom right, upper right and lower left respectively).
Object Details: While the upper bluish part of the smaller Trifid Nebula is dust reflecting the light of stars, and so is aptly known as a reflection nebula; the largest objects in this image, including the lower bright portions of the Trifid, are giant star forming regions known as emission nebulae, composed mainly of hydrogen, much of it is ionized (heated / energized) by radiation from nearby and imbedded stars.
The Lagoon Nebula (a.k.a Messier 8 / NGC 6530) is a massive star-forming region located between 4000 and 5000 light-years from Earth and spanning a region of space 110 by 50 light-years in size. The nebula's glow is due to the extremely hot O & B type stars which make up the scattered open star cluster (i.e. NGC 6530). Having formed from the material of M8, at a 'mere' 2 million years old the cluster is very young (relatively speaking) and has carved out a cavity in this enormous cloud of interstellar dust and gas. The Lagoon can be found just above the spout of the Teapot asterism in Sagittarius and has a visual magnitude of 6 and apparent dimensions of 90 by 40 arc-minutes (i.e. three by one and one-third full moons in apparent width by height), as such it is visible to the naked-eye as a small oval patch of light in reasonably dark skies. Although not rising very high above the horizon from mid-northern latitudes, it is a wonderful object for binoculars and small telescopes. Getting it's name from a 'lagoon-shaped' dusk lane which runs through the center of the nebula, when viewed through a larger instrument from a dark location the interplay of it's hot, bright stars, interstellar dust clouds, and light & dark nebulae can be truly mesmerizing!
The Trifid Nebula (a.k.a. Messier 20 / NGC 6514), is a combination of an emission nebula (bottom), a reflection nebula (top), a dark nebula (trisecting the emission nebula and cataloged as Barnard 85) and an open star cluster. Approximately the same distance from Earth as the Lagoon, M20 spans over 40 light-years in diameter. Extremely young (relatively speaking); at a mere 300,000 years old it is believed to be one of the youngest emission nebulae known. Glowing at magnitude 6.3 with an apparent diameter of 28 arc-minutes (e.g. approximately the size of the full moon), it is visible in binoculars and lies just two degrees from the larger and brighter Lagoon Nebula.
IC 4685 is often overshadowed by it's more prominent neighbors, M8 & M20, and as such it is rarely imaged by itself and more frequently as part of a shot including the Lagoon. This area consists of several individual objects of various types: the top-left 'bulbous-shaped' region, being an emission nebula, is catalogued as IC 1275; the center section (IC 4685 itself, also an emission nebula) is somewhat bisected by a dark nebula, appearing like a sinuous, meandering 'river' running from upper-right to lower-left, it is a cloud of dark obscuring interstellar gas and dust known as Barnard 303; while the brighter 'bow-shaped' portion at the river's lower-left end, emission nebula NGC 6559, has to it's immediate lower left is a somewhat roundish reflection nebula.
Within all these emission nebulae can also be found many smaller, dark objects known as 'Bok globules' - dense clouds of interstellar gas and dust under contraction that can lead to the formation of new stars and planetary systems.
Imaged Details: Taken by Jay Edwards on June 19, 2023 from the scope field of Cherry Springs State Park in PA during CSSP's 2023 summer star party. The image utilized an Orion ED80T CF (i.e. an 80mm, f/6 carbon-fiber, triplet apochromatic refractor) connected to a Televue 0.8x field flattener / focal reducer with an IDAS dual narrowband Hydrogen-alpha / Oxygen III filter and an ASI2600MC Pro camera running at -10 degrees centigrade and controlled by an ASIair running on an IPad Air. Guided by an ASI290MC autoguider / planetary camera in an Orion 60mm, f/4 guidescope; they ride on a Losmandy G-11 mount running a Gemini 2 control system.
This is one of two Losmandy G-11's in my observatory and it was the first time this G-11 mount was away from the observatory I built at my home here in upstate, NY in the past 20 or so years. Since I have two G-11's I am leaving the newer one in my observatory while using this one as a new portable / transportable system for on-the-road events like this summer's CSSP.
Given that I was simply testing out this new imaging rig that weekend, although due to the large brightness difference between the inner portions of the Lagoon Nebula and the fainter nebulosity in the image I would normally use an HDR approach varying the exposure, the data for the attached is a relatively short stack of twenty-one exposures all 3 minutes in length (i.e. 'lights'); so the image only contains a total of 63 minutes of integration time (excluding darks, flats and flat-darks) and was processed in a blend of HOO, SHO & Foraxx palettes using a combination PixInsight and PaintShopPro. As shown here the entire composite has been re-sized down to HD resolution and the bit depth lowered to 8 bits per channel.
A rendering of this data in just an HOO palette (H-alpha assigned to the red channel and OIII to both the green and blue) can be found at the link attached here:
www.flickr.com/photos/homcavobservatory/53012789409/
Having also purchased an IDAS Oxygen III / Sulfur II dual band filter later in the summer, I'm looking forward to trying these types of alternate palettes on some objects I captured the H-a, OIII, and SII data for when I was back at cherry springs state park for the Black Forest Star party in September.
Wishing a Happy Thanksgiving to all who celebrate !

A submarine is a ship designed to operate and navigate under its own power underwater. A true submarine has self-contained life support, propulsion and buoyancy control systems.
Dutch inventor Cornelius Drebel built the first known submarine in 1620. Built of wood and covered with leather, Drebel's craft carried 12 oarsmen and several passengers below the surface of the Thames in London. Oxygen was supplied by tubes connected to the surface allowing it to stay submerged at shallow depths for hours at a time.
In 1775 David Bushnell, an American engineer, developed a submarine called Turtle. The egg-shaped Turtle was operated by a hand-cranked propeller, employed hand-pumped ballast tanks and had no air supply. It could only remain submerged for about 30 minutes. The Turtle was the first military submarine. Intended for use against the British during the American Revolution, it never succeeded in sinking any target.
In 1800 the American inventor Robert Fulton built a submarine called Nautilus. The Nautilus was shaped much like a modern submarine. Fulton's design included diving planes for horizontal and vertical control and compressed air for life support and ballast control. It was powered underwater by a hand-cranked propeller, and on the surface by a sail.
During the American Civil War, the Confederate Army produced four military submarines. Each was built of iron and powered by a hand-cranked propeller. One of the submarines, the Huntley, attacked the Union's USS Housatanic in 1864. Both vessels sank as a result of the attack.
John P. Holland dramatically advanced the development of submarines. The Irish-American inventor began designing and building submarines in the late 1800s. His submarine, the Holland, was launched in 1898 and employed a gasoline motor for surface cruising and an electric motor for underwater cruising. The Holland became the first U.S. Navy submarine in 1900. John P. Holland's company eventually became the Electric Boat Company, which launched Aluminaut in 1964.
Simon Lake, an American engineer, was also developing the design of the submarine in the late 1800s. In 1887 he launched the Argonaut, the first submarine to operate successfully in the open ocean. Simon Lake sailed the Argonaut from Norfolk, Virginia, to New York in 1898. Towards the end of his life, Lake met J. Louis Reynolds and helped inspire the design of Aluminaut.

AKSM-32100D is a trolleybus with a transistorized control system based on IGBT modules and an AC induction motor, equipped with accumulators based on lithium-iron-phosphate batteries with a reserve of autonomous travel up to 30 kilometers. Unlike base model AKSM-32100, it is equipped with a 150 kW traction motor. The first three ones were delivered to Ulyanovsk, Russia at the end of 2015. In 2016-2019 St. Petersburg received 35 ones, others were delivered to Belarus cities (5 to Grodno, 4 to Gomel, 4 to Vitebsk). In 2021, they were delivered to Belarus capital Minsk (25 ones) and Vratsa (9). In December 2021, three more restyled trolleybuses came to Grodno to operate the new route 24.
АКСМ-32100D trolleybuses are produced by the Belarus company Belkommunmash (BKM; Производственное Объединение «Белкоммунмаш», БКМ). BKM was organized in 1973 on the basis of the streetcar and trolleybus repair shop under the Ministry of Municipal Economy of the Belarusian Soviet Socialist Republic. During the first two decades the plant was repairing trolleybuses and streetcars of Minsk. After USSR breakage the independent Belarus got a strong incentive to develop its own vehicles production. Therefore a few articulated trolleybuses YMZ T1 (ЮМЗ Т1) were assembled at the plant in 1993 from engineering sets of Yuzhny Machine Building Plant of Ukraine. The enterprise also modernized trolleybuses of the ZIU models 100 - 101 produced by the Engels Electric Transportation Plant (later CJSC "TrolZa") in Engels, Saratov region of Russia. Later the company started to develop its own trolleybus models, the first model AKSM 201 (АКСМ 201) appeared in 1996, followed by models 213, 221, 321 (as in foto) and 333. Since 2000 the production of streetcars started: AKSM-1M, AKSM-60102. In 2016, the production of electric buses has been organized. Today the BKM Holding (ОАО «Управляющая компания холдинга «Белкоммунмаш» - ОАО «УКХ «БКМ) is the leading industrial enterprise in Belarus in the field of production and overhaul of rolling stock of urban electric transport.
