Look! Up in the sky! Is it a bird? Is it a plane?

Picture of a rainbow in high level cirrus

None of the above. And it isn’t a UFO, either.

I took this photo an hour or two after sunrise. The sun is quite a way to the left of this image. What’s happened is that sunlight has been reflected and refracted within the ice crystals of the high level cirrus cloud, producing a blindingly white object with a halo of colour.

No wonder primitive people were superstitious.
