Tom, They are call moonbows. I haven't seen one or photographed one personally, but I understand that if you expose for a long enough period, the camera can pick up the rainbow colors in the nighttime "bow" that are too faint to see with the eye. Because the Moon is high this time of year, this is the season for Moon halos - which is just a Moonbow that covers 360 degrees because it is not cut off by the horizon. Moon halos also occur between the observer and the Moon, while Moonbows occur behind the observer with the Moon at the observer's back. - Kurt P.S. - Wonder if they can be seen or photographed around the Utah Bridal Veil Falls? Kim, are you there?
