No, you're not seeing triple. On Sunday morning, a sun dog took over Moscow's sky, giving the illusion of three suns.

Sun dogs, scientifically called parhelions, are a atmospheric phenomenon that create the appearance of multiple suns: The real sun in the center, and two bright halos on either side. They occur when sunlight is refracted through ice crystals in the air, the National Oceanic and Atmospheric Administration explains. That means they normally show up during winter.

The sun dog was recorded in a 2-minute video taken from a metro train. Outside, it was about -4 degrees.

Pro tip: fast-forward to 0:30 for the best shot of the triple-sun. During other parts of the clip, the sun disappears behind the city's skyline as the train chugs through Moscow.
