Thunder Bolt
Silly old bat
Monday night I was in Lapland. It was a cloudy night. My bedroom window looked across a frozen river. On the other side of that river was a treeline with next to nothing in the way of civilisation beyond it. Certainly no towns or villages. But the clouds were illuminated bright white and pink. But it wasn't green and whispy and moving like on all the picture perfect vids and postcards you ever saw. So you automatically start scrabbling around for other explanations to explain away what you're seeing.
Some northern lights are red so maybe the clouds were diluting the red colours?
