Posted on 06/28/2016 10:40:43 AM PDT by SunkenCiv
Explanation: What's happening over the horizon? Although the scene may appear somehow supernatural, nothing more unusual is occurring than a setting Sun and some well placed clouds. Pictured above are anticrepuscular rays. To understand them, start by picturing common crepuscular rays that are seen any time that sunlight pours though scattered clouds. Now although sunlight indeed travels along straight lines, the projections of these lines onto the spherical sky are great circles. Therefore, the crepuscular rays from a setting (or rising) sun will appear to re-converge on the other side of the sky. At the anti-solar point 180 degrees around from the Sun, they are referred to as anticrepuscular rays. Featured here is a particularly striking display of anticrepuscular rays photographed earlier this month in Westminster, Colorado, USA.

I also agree, and will add that I’ll take Crepuscular rays over Anticrepuscular rays any day, for they are obviously superior.
Caused by dense clouds of smoke? :)
I know right where this is; I lived less than a mile from this spot, if anyone cares!
The accompanying video pinned the antisuckometer. :-)
And, yes, I too prefer the Crepuscular rays over Anticrepuscular rays! :-)
Well then, looks like you live in a pretty area! :)
Don’t be so harsh!
It’s an interesting atmospheric effect! The items that cause the shadows could be a 100 miles away from you.
And remember, they are parallel.
It’s in Colorado, so, I’ll estimate, much more than 100 miles. ;’)
