Found this, it's pretty cool.

A ghostly image captured on camera by a photographer in North Yorkshire shows a night-time rainbow created by the light of the moon.

An idea, like a ghost, must be spoken to a little before it will explain itself!

Wow.  My God, that is beautiful.

PPI Karl

Stunning.  Is this what people call a "moon-dog," or am I thinking of something else?
If you want to end your misery, start enjoying it, because there's nothing the universe begrudges more than our enjoyment.

I thought that was a "Moon-Pie"?  Sorry....bad joke.  I'm just hungry.

So, before Karl hurts me baaaaad........is it called a "Moon-Dog"?

Moon dog
From Wikipedia

A moon dog or moondog (scientific name paraselene, plural paraselenae, i.e. "beside the moon") is a relatively rare bright circular spot on a lunar halo caused by the refraction of moonlight by hexagonal-plate-shaped ice crystals in cirrus or cirrostratus clouds. Moondogs appear to the left and right of the moon 22? or more distant. They are exactly analogous to sun dogs, but are rarer because to be produced the moon must be bright and therefore full or nearly full. Moondogs show little color to the unaided eye because their light is not bright enough to activate the color photoreceptors in humans.

Ah yes, a moonbow.  :)

I have tried to capture them on camera but I have never been successful. They are beautiful, aren't they?

Moonbow!  I like that!   :D

Yes, it is quite beautiful and I have never seen anything like it.

That is a night time rainbow. It is not a moonbow. I have seen a moonbow. It is white in color and has no other color.
This picture has color in the bow
I would have loved to have seen that. I believe those are quite rare.
I love things like this.
I'am a weather nut. :)
Sounds interesting...Go on.

It's a long exposure photograph -- that's why it picked up color that the eye cannot percieve, like pictures of nebula in outer space. A moonbow is a night time rainbow. Some are brighter than others, but all are cause by light refracting from a bright moon rather than the sun.

The one I saw, with my own eyes, in Yosemite was at night with no fog and it had no color but white. It was awesome. The only rainbow colors I have ever seen at night were around the moon. I guess if you have a camera taking a long exposure you would get more color. I would still like to see a full color rainbow at night.
Sounds interesting...Go on.
