The National Weather Service says sun dogs are colored spots of light that develop due to the refraction of light through ice crystals.They are located approximately 22 degrees either left, right, or both, from the sun, depending on where the ice crystals are present.The colors usually go from red closest to the sun, out to blue on the outside of the sun dog. Sun dogs are also known as mock suns or parhelia, which means "with the sun".Thank you for all the great photos!
