Strange cloud

So the other day Amber was off to Emmas around the corner, and she popped back in and said "Mum, there's a really weird cloud out here..." And sure enough, there was.

Now either a crazy plane had been going around in circles for a while, then disappeared without any cloud trail, or some strange freaky weather created it. Whichever it is, I think it's beautiful.

If you look at the bottom of the pic, you can see other people in the street marvelling at it's craziness.
