WATCH: Moscow commuter captures sundogs around the sun on video

TORONTO – Aside from the skiing, snowboarding and other fun things to enjoy during the winter, one of the things the cold weather provides is beautiful atmospheric phenomena.

A commuter on a train in Moscow captured a pair of sundogs — caused by light refracting through ice crystals in the atmosphere — on Jan. 19.

Though sundogs (the scientific name is parhelia, or parhelion in the singular, which is Greek for “beside the sun”) are also visible in summer, they are most likely to be viewed when the atmosphere is particularly cold. They often accompany halos around the sun.
