The discussion here has yielded nothing.

Thank you!

Consensus: Crepuscular Rays

Answer 1

Another option is that these are not anti-crepuscular, but twilight rays

There are very similar photos

Answer 2

This is a shadow.

Answer 3

I also tend to the version that these are twilight rays :

At twilight, one can observe a phenomenon when clouds leaving for the western horizon cast streaks of shadow over the entire sky, like a giant fan. These bands come from an imaginary point below the horizon where the Sun is. Just like the rays of the sun "drinking water", only this time the sky is completely clear and we see how the dark rays stand out sharply against the purple light. They can be seen not only in the west, where the Sun sets, but sometimes in the eastern sky.

Answer 4

Yes, this is a twilight ray, or, more simply, a shadow from a cloud or mountain. Only here the object that casts the shadow is beyond the horizon.

Answer 5

Are you an eyewitness?

Answer 6

>>With exceptionally high air transparency, the last beam can be green-blue and even blue. Such a phenomenon is extremely rare.
Isn't it?
