Rainbows are a frequent sight in Hawaii thanks to brief showers and plenty of sun shine. But one creature, the moonbow, or lunar rainbow, is especially rare. This type of rainbow is caused by the light of a full moon.
We were lucky enough to get this photo of a double moonbow in Kauai. The colors of the rainbow were dim but clearly visible. Using a tripod with the shutter speed set to about 20 seconds the colors are brighter in the photo than they were with the naked eye. The camera also revealed the faint second rainbow. The picture was taken about 1.5 hours past sunset.
