Colorado CR 69
A rare sight: Double "Sundogs", or "Parhelion" as this atmospheric optical phenomenon is called in meteorology lingo, captured in full, magnificent display over the Rocky Mountains in South Central Colorado. Sundogs are halos caused by the refraction of sunlight by ice crystals in the atmosphere. These ice crystals act like prisms, creating the bright sundogs on the left and right sides of the sun at an angle of 22 degrees. Sundogs are always red-colored at the side nearest to the sun and then grading from orange to blue on the outside.
