This very rare form of rainbow - sometimes called a fire rainbow - is caused by the angle of the sunlight hitting cirrus ice crystals in the atmosphere. The effect is fleeting, usually only lasting a few seconds before either disappearing or turning normal-cloud white.

This was spotted June 5 in a suburb of Atlanta, Georgia.

Some think fire rainbows are where the concept of dragons came from.

The fire rainbow is play of light weather phenomenon, a form of Circumhorizontal arc.❤
