Have you ever seen a 'Moonbow'?
A moonbow (also known as a lunar rainbow,lunar bow or white 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 from the surface of the Moon. They are always in the opposite part of the sky from the moon.
It is difficult for the human eye to discern colors in a moonbow because the light is usually too faint to excite the cone color receptors in human eyes. As a result, they often appear to be white. However, the colors in a moonbow do appear in long exposure photographs.
Here is a magnificent one captured at Victoria Falls, Zambia.
However, you don't have to travel that far to see a moonbow and we had our own here in the UK last weekend, at Richmond, North Yorkshire.
Not so brilliant as the one in Zambia, but still quite impressive.
Photographer Chris Walker captured the picture as he was driving through a storm around 7pm last Sunday.
He said: 'I noticed something odd in the sky as I was driving home.
'A near full Moon was behind me and the wind was blowing a gale and rain was being driven from clouds on the horizon.
'The Moon was so bright that when I arrived home it was obvious that the object in the sky was a rainbow illuminated by moonlight.
Mr Walker only needed a 30-second exposure on his Lumix digital camera to reveal the full range of colours.
'The moonlight was so bright I could see red in the rainbow with my unaided eye,' he said.

One night last spring when we were all up very late, I came out to the deck and there it was, a moonbow. I had never seen one before. They are quite amazing.
