Sun Dog

My father recently photographed, with his cell phone, the atmospheric phenomena called a Sun Dog, or more formally, a Parhelion. It is caused by the refraction of light high up in the atmosphere by hexagonal shaped ice crystals, usually in Cirrus clouds. You can read the wikipedia page for more and check out the google images for some really amazing images.
