We don't see sun dogs very often here in Arizona, regardless of the massive amounts of sunlight that we have. Sun dogs are part of a halo around the sun, only seen when the conditions are right and ice crystals form in the atmosphere. In those cases, you will see a halo around the entire sun, but the areas directly left and right of the sun will appear brighter. Sometimes these brighter areas are the only parts of the halo that appear. These are sun dogs.
