What is that small rainbow near the sun? And that faint rainbow above it in the clouds?
A sun dog, phantom sun, mock sun, or parhelion, is a light appearing in the sky at the same elevation as the sun and 22° away from the sun. The distance from the sun is always the same because hexagonal ice crystals in the atmosphere refract the light at a consistent angle.
Sundogs are members of a larger family of halos created in this way, and can appear as pillars, small rainbows, or arcs that form a halo around the sun.
