Interesting photo
 
I went for a quick oil stirring flight last night. The sun was setting and a rather ordinary sunset began to unfold.... the first picture. After a minute it transformed to the second picture. I can't begin to understand the what/why/how the straight and evenly spaced lines came from. Just thought I'd share this interesting photograph.
It almost looks as if they were shot on different days. I took them myself only a couple minutes apart.

Meteoptics illusion
 
The anticrepuscular rays maybe? :)

Send them to James Spann and ask him. I am sure he will know.

Crepuscular rays.

Shadows of the "Kelvin-Helmholtz" waves...
 
I think it the rays from the setting sun shining over a nice Kelvin wave formation (and no, I'm not making this name up either!)
They are very short lived so that explains the quick pop-up!
Very cool

Interesting photo!
 
Paul,

What a great photo. It does look like maybe the shadow of the light hitting to Kelvin Helmholtz waves. What is cool is that the shadows appear to be associated with the trough, not the peak of the waves. Very cool in any event!

cheers

Hey and thanks to everyone for your responses. I'm learning everyday as I've never heard of this phenomenon. Interesting stuff!

I saw the same phenomenon on an evening flight two weeks ago.

Before...


After...

Amazing capture. No expert, but I specialize in sunrises and sunsets (see my YouTube channel)... and these were just beautiful.
