Weather Tidbits: Sun Dog

The illusion of multiple suns occurs in this Weather Tidbits, with the sun dog. A sun dog is a colored luminous spot by the refraction of light through ice crystals that appear on either side of the sky. They are known as parhelia or mock suns, creating the illusion of 3 suns; and often appear in conjunction with the 22° halo. Sun dogs will appear with the same brightness on both sides and are associated with high clouds. A moon dog will occur if the moon’s is extremely bright with a quarter moon or greater.
