I could swear the sky was reddish as I went to bed last night, in Stockholm... it was rainy, but as I turned off all lights I noticed an unfamiliar, slight red tint. I thought that maybe it was some neighbour's light reflecting (probably was) but seeing the Tasmanian skies in the photos made me think it might've been Aurora as the color is very similar!
I haven't seen anything in the news, but apparently some cities in Russia also reported Aurora sightings pretty far south.
Aunty sent me pictures of this night aurora in Latvia... it is more southwards than Stockholm. I was amazed. And sorry that I didn't know I had to be up to see it too for the first time in my life... eh
