A moonbow (also known as a lunar rainbow, white rainbow, lunar bow or space 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  and they are always in the opposite part of the sky from the moon.  A true moonbow is lit from the Moon itself.  Moonbows are most easily viewed when the moon is near to full (when it is brightest) and for true moonbows, other than those produced by waterfalls or sprays, the moon must be low in the sky and the sky must be dark.  This combination of requirements makes moonbows much more rare than rainbows produced by the sun. Few places in the world frequently feature this phenomenon but Victoria Falls on the border between Zambia and Zimbabwe is widely known for moonbow occurrence.
