World’s Weirdest Weather

A natural halo is an optical phenomenon that produces a really weird looking atmospheric light around the sun. The science behind it is basically the same as for rainbows and moonbows (#8), but the halo is formed when ice crystals are refracted by the light of the sun in the upper atmosphere. Natural haloes have also been seen to form around a full moon and sometimes even around bright planets and stars. Sometimes there may be a series of circles, the one closest to the sun being the brightest.
