Setting Sun Shock Wave
I titled this Shock but I could have used Bow wave just as well. The atmospheric phenomena you are seeing here is a very complex interaction for sure. The color is real as is the wave in front of the sun. I was watching this clearly on my video eyepiece just as you see it here. The Pall of Smoke was significant even for recent standards.
Amazing light effects occur in a heavily occluded / smoky atmospheric haze. I have views looking west from the local that reach out 93,000,000 miles to the sun. Between myself and the sun are many miles of atmosphere acting as a filter to all but red and yellow light. (With all gradations in between like orange).
I think there are a lot of things going on here with the color and the gradients. You will note a baseball diamond shaped area of yellow above the sun is the highest sky where yellow can penetrate with a given intensity. (a calculus equation or two involved here I suspect chuckle). Less smoke between me and the light there. Below on the wave, only the red light can penetrate the haze. The closer to the sun, the brighter the light the haze has to block. The curve will be smooth around the base. Mother Natures Geometry at her best artist strokes. I love smooth gradients but naturally stepped gradients are massively cool. Maybe it’s just me chasing light again lolol.
I’ve seen this only a few times in my travels. I suspect it has a name but I haven’t researched it.
