What is a Sundog?

Sundog-parhelion-mock sun

I just learned what a sundog is today! A sundog is an atmospheric phenomenon that creates a luminous ring or halo around the sun, with bright spots on each side. They are created by falling ice crystals in the Earth’s atmosphere. For more information, click here. The scientific name is parhelion, and other names are sun dog (or sundog), mock sun or phantom sun. I learn something new everyday!
