Moon diamond dust halos in Lappland

This splendid display was seen last night in Sirkka, Finland. The photographer, Timo Veijalainen, tells the display lasted for about an hour after he noticed it and that the temperature was close to -10° C. Sirkka is a settlement right next to Levi ski center, from which snow guns this must have originated.
