COOL VIDEO: Viewer captures fire rainbow during drive in Galveston

An Eyewitness News viewer was lucky enough to capture a colorful fire rainbow on video in Galveston - and it was an incredible sight!

Technically, it's neither a rainbow nor fire.

The National Weather Service says it is actually called a circumhorizontal arc that forms when you have ice crystals in high clouds.

It's a beautiful sight. Grab your camera if you see another fire rainbow!
