I saw this on snopes.com. It is real, way toooooo cool!!:clap_1:


THIS IS A FIRE RAINBOW ? THE RAREST OF ALL NATURALLY OCCURING ATMOSPHERIC PHENOMENA.

THE PICTURE WAS CAPTURED ON THE IDAHO/WASHINGTON BORDER. THE EVENT LASTED ABOUT 1 HOUR.

CLOUDS HAVE TO BE CIRRUS, AT LEAST 20K FEET IN THE AIR, WITH JUST THE RIGHT AMOUNT OF ICE CRYSTALS AND THE SUN HAS TO HIT THE CLOUDS AT PRCEISELY 58 DEGREES.

Origins: This is a real photograph of an atmospheric phenomenon known as a circumhorizon(tal) arc, the example shown above was captured on camera as it hung for about an hour across a several-hundred square mile area of sky above northern Idaho (near the Washington border) on 3 June 2006.

In general, a circumhorizontal arc (or "fire rainbow") appears when the sun is high in the sky (i.e., higher than 58? above the horizon), and its light passes through diaphanous, high-altitude cirrus clouds made up of hexagonal plate crystals. Sunlight entering the crystals' vertical side faces and leaving through their bottom faces is refracted (as through a prism) and separated into an array of visible colors. When the plate crystals in cirrus clouds are aligned optimally (i.e., with their faces parallel to the ground), the resulting display is a brilliant spectrum of colors reminiscent of a rainbow.

:clap_1: ...MeWOW!!! That was beautiful!
 
Cool picture. I love phenomena like this.
About ten years ago the younger son and I were walking outside to the car when we saw this up in the sky. We could not for the life of us figure out what it was. It wasn't a rainbow, but it sure was something.
Other people stopped when they saw us craning our necks gazing at this "cloud rainbow" (that's what we called it) and nobody knew what we were looking at, just that it was really cool. We stood there for about 20 minutes, watching it, then we finally left, and it was gone when we came back.
It's hard to judge, but I think that the fire rainbow we saw in Colorado was much smaller than the Idaho one pictured.
