ring around moon
Moon's ice circle
A ring around the moon is a luminous halo caused by moonlight refracting through ice crystals in high, thin clouds.
The phenomenon appears as a pale circle surrounding the moon, typically at a fixed radius.
Folk wisdom holds that a ring around the moon predicts rain or snow, which has some basis—the cirrus clouds that create halos often precede weather fronts.
