Rainbows do occur at night

Moon rainbowIt was previously thought that rainbows never appear at night. However, rainbows do appear at night and is known as moon rainbows or lunar rainbows.

To see a moon rainbow, many conditions must coincide:

1. there must beĀ  a full moon,

2. the moon must be either rising or setting,

3. and there must be mist in the air because a rainbow is made up of the rays of the sun that are reflected inside raindrops – or, in this case, the rays reflected by the moon.

Moon rainbows are a rarity; there have been only a few in the past 50 years.
