A 22° halo is an atmospheric optical phenomenon that consists of a halo with an apparent diameter of approximately 22° around the Sun or Moon. Around the Sun, it may also be called a sun halo. [1] Around the Moon, it is also known as a moon ring, storm ring, or winter halo.
Also known as a lunar halo, a bright white ring of light around the moon can appear anytime during the lunar calendar and at any time of year, especially in winter.

A ring or halo around the moon tonight? That lunar halo is caused by the refraction of moonlight by ice crystals, creating a circle effect.
A Lunar Halo, also known as a 22-Degree Halo, is a hazy ring that occurs around the moon at a radius of approximately 22 degrees. It results from the moon's light being refracted by ice crystals in Cirrus clouds in the upper troposphere at an altitude of approximately 6000 meters or 20 000 feet.
Spying a bright Moon with a ring around it high in a cold winter sky is a beautiful, and even spooky, sight. But you can spot Moon halos any time of year — and the same phenomenon occurs...
If you've ever looked up at the full moon in the night sky, you may have noticed a large halo of light around it. But why does this lustrous ring sometimes encircle our natural satellite?
This ring surrounding the Moon is caused by the refraction of Moonlight (which is really reflected sunlight, of course) through ice crystals suspended in the upper atmosphere between 5-10 km in...
