A sun halo is an optical phenomenon produced by ice crystals creating colored or white arcs and spots in the sky. Many are near the sun or moon but others are elsewhere and even in the opposite part of the sky. Commonly referred to as a 22-degree halo, it forms a ring exactly 22-degrees from the sun.
