Upside down rainbow

I have had several people inquire about the upside down rainbow. So I googled it, cause I knew someone else could explain it better then me. This is what it said:

"What looks like an upside-down rainbow is actually a rare atmospheric spectacle called a circumzenithal arc. According to the San Francisco Chronicle: “it’s an unusual phenomenon caused by sunlight shining through a thin, invisible screen of tiny ice crystals high in the sky and has nothing at all to do with the rain.”

Feel free to be scientifically correct, but I’ll stick with calling it an “upside-down rainbow” … “circumzenithal arc” just doesn’t have the same pizzaz.

I really think I'll call it a RAINBOW SMILEY!
