 A sun dog is shown reflecting in the thin clouds. The true sun is outside of the picture to the right. A sun dog is an uncommon type of halo, or an atmospheric optical phenomenon associated with the sun. The scientific name for the phenomenon is parhelion (Plural parhelia). It occurs due to internal reflection in ice crystals which accounts for its relative rarity - it is only produced in clouds cold enough to be ice rather than water, which only occurs far below 0°C. These clouds are usually thin and high up. Sundogs (and other associated phenomena such as sun pillars) are common in Antarctica. They occur horizontally either side of the sun at an angular separation of 22 degrees.
