Sundogs

"Sundogs are visible when the sun is near the horizon and on the same horizontal plane as the observer and the ice crystals. As sunlight passes through the ice crystals, it is bent by 22 degrees before reaching our eyes, much like what happens with 22 degree halos. This bending of light results in the formation of a sundog."



Sundogs are fairly common occurrences in the Arctic and Antarctic. They form when the sun is near the horizon and ice crystals high in the sky line up in a way that bends the solar rays like a prism.
