I saw one of these in Peru! Fire Rainbow The correct name is circumhorizontal arc. This actually is an ice halo formed by platter shaped crystals of ice up above in the sky. The colors are formed through the same procedure as in common rainbows.
A volcanic eruption on the Fimmvruhls mountain pass in Iceland is pictured with the Aurora Borealis in the sky behind. A British photographer has captured the rare and beautiful aurora borealis shining brightly over an erupting volcano.
Fire rainbows are the rarest of all naturally occurring atmospheric phenomena. For a fire rainbow to occur, cirrus clouds must be feet in the air with the precise amount of ice crystals, and the sun must hit the clouds at 58 degrees. (a/k/a Sun Doggies)
