Sun Rays Among the Clouds

Sun Rays

Last evening, we were bringing the dogs back from walking when I noticed the sun rays among the cloud build ups over the house. I call this effect a “glory,” but it does have a technical name, crepuscular rays.

Wikipedia has this about crepuscular rays:

Crepuscular rays (also known as God rays) in atmospheric optics, are rays of sunlight that appear to radiate from the point in the sky where the sun is located. These rays, which stream through gaps in clouds (particularly stratocumulus) or between other objects, are columns of sunlit air separated by darker cloud-shadowed regions. Despite seeming to converge at a point, the rays are in fact near-parallel shafts of sunlight and their apparent convergence is a perspective effect (similar, for example, to the way that parallel railway lines seem to converge at a point in the distance).

The name comes from their frequent occurrences during crepuscular hours (those around dawn and dusk), when the contrasts between light and dark are the most obvious. Crepuscular comes from the Latin word “crepusculum”, meaning twilight
