Up to OJB's Photos List Crepuscular Rays Crepuscular rays are formed when the Sun's rays are interrupted by patches of cloud, and the rays which do get through illuminate thin cloud further up the sky. They are really parallel, but they appear to diverge as they get closer to the observer higher in the sky. There are also anti-crepuscular rays which form on the opposite side of the sky from the Sun, but these are a lot less common. |
