"Crepuscular rays are alternating bright and dark rays that appear to radiate from the Sun's location at a time when the Sun itself is hidden by clouds either below or above the horizon. The scattering of sunlight by haze, dust, or mist in the air enhances the contrast between rays."

-from National Audubon Society Pocket Guide: Clouds and Storms, 1995
