Anticrepuscular rays (DI01610), Photo by Carlye Calvin
Anticrepuscular rays are similar to crepuscular rays, but seen opposite the sun in the sky. Anticrepuscular rays are most frequently visible near sunrise or sunset. These anticrepuscular rays were seen at sunset in Boulder, Colorado. Crepuscular rays are usually much brighter than anticrepuscular rays.
