Nuclear Explosion Over North Yorkshire

[nivrip]

I was out hiking today and I saw this...………………

It was a fairly dull day, hence the darkish picture. But this just looked so odd with the concentric circles of cloud.

Can't say I've seen anything like this before and wondered if anyone has any ideas just what might have caused it (apart from an atomic bomb, of course).

That's weird but very pretty! Was it a local pilot doing doughnuts in the sky?!

I've only just seen this thread now @nivrip - that's a really interesting cloud formation and I've got no idea what it means. I tried googling for what it could be, but then got images of people talking about chemtrails, etc... so I gave up .

Could be the movement of the wind in the upper atmosphere.
