MOONBOW
The closet relative to a rainbow, the moonbow (or lunar rainbow) is a formation of water droplets, mist and light.
Unlike a rainbow, a moonbow is produced by light reflected from the moon, which mingles with the droplets of water and spraying mist, usually from a waterfall.
Because of the faint light emitted from the moon, moonbows are extremely elusive, and their colours hard to discern. However, there have been many sightings, particularly at Yosemite Falls in California, Cumberland Falls in Kentucky, Victoria Falls Zambia/Zimbabwe, and Waimea on Hawaii. Moonbows are also easily viewed when the moon is full, and can also be produced when the moon is low in the sky, and the rain is falling opposite.
