I saw a picture tonight of a phenomena called a fire rainbow. I had never heard of it before, but when I saw a picture of it, I was blown away. It is one of the rarest natural occuring atmospheric phenomena around. The picture I saw occured over the Idaho/Washington border. It happens when cirrus clouds, at least 20K feet in the air, with just the right amount of water crystals in it, gets hit by the sun at precisely 58 degrees. It was beautiful. I wasn't able to load the picture up but if anyone wants to see it I can e-mail it to them. I was also wondering, has anyone ever seen a fire rainbow before?
