Moon Halo The moon satellite

This photo was captured when tall, thin clouds containing millions of ice crystals covering much of the sky. Each of the ice crystals acts as miniature lenses. This occurs because most of these crystals have an elongated hexagonal shape and the light that enters through one of the faces of these crystals is refracted on its opposite side just at 22 degrees, which corresponds to the radius of the lunar halo.

A similar phenomenon is the solar halo that can be visible during the day. This picture was taken in Lansdowne, Pennsylvania. Jupiter appears to the left of the Moon.

Sometimes a second halo is distinguished caused by the refraction of ice crystals around the main halo at a distance of 46 ° from the center of the Moon.
