Sundogs, February 25, 2003. The bright spots on either side of the sun are called sundogs. On this cold winter morning flat, hexagonal shaped ice crystals were gently falling high in the atmosphere and they were refracting the light at a point 22 degrees on either side of the sun back toward the camera. The light column rising above the sun was made by sunlight reflecting off of the undersides of the flat ice crystals. This photograph was featured on the SpaceWeather website.
