Anti-crepuscular rays
Polecat Bench. January, 2012
The term for rays cast by the setting sun is crepuscular--associated with twilight. They are caused by light passing through holes in the clouds, and they are actually parallel. It's a trick of perspective which makes it appear they originate from a single point. This photo was taken at sunset; it faces mainly to the east. Since the rays appear to be opposite the setting sun, they are called anti-crepuscular rays.
