Its lovely isnt it? Warms the cockles on a cold night🙂
Sadly tor eport, I dont think people do know. I didnt venture out myself to take this pic, although I can see the eye from my roof, this was taken by someone at work on the London Ambulance Service- who didnt know why it is blue!
In all fairness, it changes colour all the time. I will be going up on my roof tonight to see if it has gone back, which I hope it has so that people realise it was a feature for the day only.
