Daily Postcard: Sun Dog Over Los Alamos Wednesday

Daily Postcard: A sun dog is spotted in the sky Wednesday evening above Los Alamos. According to skyandtelescope.com, a sundog, or mock Sun, is a concentrated patch of sunlight occasionally seen about 22° to the left or right of the Sun. Sundogs often form when sunlight refracts through icy clouds containing hexagonal platecrystals aligned with their large, flat faces parallel to the ground. Technically known as parhelia (singular parhelion) they are often white but sometimes quite colorful, looking like detached pieces of rainbow, with red on the inside, toward the Sun, and blue on the outside.
