Rare lunar halo circles the Moon in stunning nighttime display

BGUK_3432540 - A rare Lunar Halo seen around the Moon. A lunar halo, is an optical phenomenon caused by the refraction of moonlight through ice crystals in high-altitude clouds. These hexagonal ice crystals bend the light, creating a circular halo that is typically about 22 degrees in diameter. This can sometimes be a sign of an approaching storm, as the cirrus clouds that cause the halo often precede a warm front.
