Moonbows are a similar phenomenon to rainbows, but as opposed to rainbows, instead of the arched bow of color being produced by sunlight refracting off moisture (usually drizzle or rain) in the air, the color is produced when light is reflected off the moon’s surface. Moonbows are generally much fainter than rainbows, simply because the volume of light reflected off the moon is considerably less than that reflected from direct sunlight. To photograph a moonbow, one needs to use a long exposure.
