Mock Moon

Description

A member of the halo family, paraselene, also commonly known as a moon dog or mock moon, is an atmospheric optical phenomenon where bright spots or "mock moons" appear to the sides of the Moon, caused by light refracting through high-altitude hexagonal ice crystals in cirrus or cirrostratus clouds. They are analogous to Parhelia (sun dogs) and are most often seen during a full moon.
