These photographs of iridescent clouds, taken from the garden at 9.10am on the 10 December are known as nacreous or mother of pearl clouds and are formed some 15 -25km high in the stratosphere at temperatures below -78C.
They most commonly appear in polar regions but it is apparently quite rare to see such good displays in the UK. The clouds play a part in the formation of ozone holes as they contain chemicals which destroy ozone. (Information from the Met Office).

Thanks for that. I admit to never having heard of that cloud type.
Aha! Laura saw these too!
:-)
Your photos are better than mine......
Me neither Alan.
Hi Alan
Lots of sitings apparently.
Aberdeenshire seems to have been particularly favoured Laura. I can't take credit for the photos - I just pointed the camera and pressed the button!
OOps! My naughty dithering computer mouse accidentally deleted your comment on my blog - please send it again......
I've got dithering mice in the garage I think, but I try to keep them away from computers Laura.
Very interesting Gibson - lovely clouds.
Hi Matin
Neither of us had heard of them, let alone seen them, but Lynne immediately described them as 'mother of pearl' clouds!
