We All Know Rainbows But Have You Ever Seen a Moonbow – A Night Rainbow Lit By the Moon?

This set of requirements makes moonbows much rarer than solar rainbows – they actually occur less than 10 percent as often as normal rainbows. Sometimes moonbows can also be observed during full moonrise during the winter months, when the sky is darker and rain falls at extreme latitudes. The definition of the colors is subject to the size of moisture drops present in the air: the smaller they are the less vivid the colors will be.
