Fire Rainbows

I had never heard of "fire rainbows" before!

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.
