    Anticrepuscular Rays Over Horseshoe Canyon

    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. While enjoying the sunset after dinner near Horseshoe Canyon in Utah, the photographer chanced to find that an even more spectacular sight was occurring in the other direction just over the canyon -- a particularly vivid set of anticrepuscular rays.

    A large version of this piccy can be found here, this is a 178K Jpeg image.

    Nice one S'ah. Amazing what tricks sunlight plays (see also Pic Of The Day, 26th Jan - better do that before it gets pruned).
