AstronomyUkraine Posted October 20, 2021 Share Posted October 20, 2021 (edited) Just happened to go outside tonight, and came across this beautiful sight. This phenomenon is called a 22° halo, or moon ring. A 22° halo is an optical phenomenon that belongs to the family of ice-crystal halos. Its form is a ring with an apparent radius of approximately 22° around the Sun or Moon. When visible around the Moon, it is called a moon ring or winter halo. It forms as direct sunlight or moonlight is refracted in millions of hexagonal ice crystals suspended in the atmosphere. Sorry the image is not the best quality, it was taken with a mobile phone.

Marmot Posted October 21, 2021 Share Posted October 21, 2021 What a great image, especially considering you just came across it by chance. It’s also surprising just what can be captured with a mobile phone! Quote Link to comment Share on other sites More sharing options...
