Find Out What Caused This Double Sun in Seattle!

This was shared on Reddit.com by someone in Bellevue on Thursday. Can you guess what causes it?

It's called a sun dog, also known as phantom suns or mock suns. The scientific name is parhelion.

It's caused by the same thing as a halos (when a ring appears around the sun). Ice crystals in the atmosphere cause light to reflect and refract. They are most common when the sun is close to the horizon.
