Moonbows

Moonbows, which are also called lunar rainbows, lunar bows, and white bows, are rainbows that are made with the light reflected off of the moon.  They are very beautiful, and they appear to be a glowing, shimmering, light-colored rainbow.  Depending on the angle one observes the moonbow from, the moonbow may appear slightly different.  A light, colored halo around the moon produced by refraction in ice crystals, however, is not a moonbow.  Unfortunately, it seems that moonbows are rather uncommon, and if one ever appeared near your home, it would fade in a few minutes, so bring a camera!  The moon must be bright and full or near to full, the sky must be black, the moon must be at 42 degrees or lower in the sky, and there obviously must be rain (or mist) in front of the moon.  There also must be enough mist, but no more.  Some waterfalls produce this phenomena; the only ones that feature it frequently are Cumberland Falls, near Williamsburg in Kentucky, USA, Victoria Falls, on the border of Zimbabwe and Zambia, and Waimea Falls in Waimea, Hawaii, USA.  There is a picture of a moonbow in this post, but one should make an effort to see one in real life; spectators have claimed it is a gorgeous sight and a wonderful experience.
