Our Strange Sky: Double Moonbow Over Hawaii
Posted by mistergroonk in Just Freaking Neat, Photography, Science, USA on March 31, 2011
Because of Ethan Tweedie we learned there is such a thing as moonbows.
A moonbow (also known as a lunar rainbow, lunar bow or white rainbow) is a rainbow produced by light reflected off the surface of the moon rather than from direct sunlight.
Moonbows are relatively faint, due to the smaller amount of light reflected from the surface of the moon. They are always in the opposite part of the sky from the moon.
It is difficult for the human eye to discern colors in a moonbow because the light is usually too faint to excite the cone color receptors in human eyes. As a result, they often appear to be white. However, the colors in a moonbow do appear in long exposure photographs.
Also, we’ve got to visit Kamuela, Hawaii.
