The Sky Above Me

Day Two of Covid. The official guidance (or at leas the most up to date I can find online) still seems to be that you should stay at home and avoid contact with other people as much as possible but that you can still get outside once a day for some exercise and fresh air as long as you adhere to social distancing.
I actually didn't feel that bad at all - I've had much worse colds. So I decided to get my allotted fresh air in early and go for a socially distanced early morning run. It felt pretty good so I did some more exercise when I got back which was a bit daft and I must admit I paid for it later.
My brother tested negative yet again so he headed off to work and I just spent the rest of the day recovering from my earlier over exertions and the best I could manage was reading, some TV watching and just looking rather mournfully out the window - I was missing sitting in a nice warm pub with a pint in my hand or even being out doing some Christmas shopping (I've never said that before - it must be Covid delirium setting in!).
It was only later in the afternoon when I went out into the garden to get some washing in that I noticed this incredible sky - a myriad of glorious colours shimmering like dancing waves. The only thing I could compare it to was images of the Northern Lights but obviously they don't came as far south as the South East Of England where we are and the colours weren't the same. So I grabbed my camera and took this shot from one of our upstairs windows.
My sister later said she'd seen something on the news about it earlier and they are apparently called Mother of Pearl or Rainbow clouds.
I found out subsequently that their official name is actually Nacreous clouds and that they are rare cloud formations that exhibit vibrant and ever-changing iridescent colours. Unlike their low altitude counterparts, Nacreous clouds appear in the stratosphere where the soar at heights of 9 to 16 miles above the earth's surface. 
Their mesmerising display is most commonly observed within 2 hours after sunset, or before dawn, when they remain illuminated by the sun's rays. I feel so lucky to have witnessed it!
