Sundogs appear as duplicate suns in the sky over a Russian city.

Comment: This is the second time in 2016 that this optical illusion has appeared in Kazan:

3 suns phenomenon seen in Kazan, Russia

A rare optical illusion giving the appearance of three suns in the sky was caught on camera over a Russian city where ice crystals gathered in the atmosphere.

The video shows what appears to be three suns in the sky over the city of Kazan, but the "suns" to the left and right of the middle star are actually optical illusions known as "sundogs."

A sundog is created when the light from the sun is reflected by ice crystals in the atmosphere.

The triple sun, recorded in January, featured illusion suns much larger than those recorded in December over Winnipeg, Manitoba, following a large snow storm.
