Anticrepuscular rays
From Free net encyclopedia
Anticrepuscular rays are similar to crepuscular rays, but seen opposite the sun in the sky. They appear to converge at the antisolar point due to perspective. These are visible most frequently near sunrise or sunset. Crepuscular rays are usually much brighter than anticrepuscular rays. This is because for crepuscular rays, seen on the same side of the sky as the sun, the atmospheric light scattering making them visible is taking place at small angles (see forward scattering).
