lunar halo
Icy moon circle
A lunar halo is a ring of light that appears around the moon, caused by ice crystals in the atmosphere refracting moonlight.
The effect creates a pale, ghostly circle at a fixed distance from the moon: A lunar halo hung in the winter sky.
Folk wisdom holds that a lunar halo predicts approaching rain or snow.
