I'm just writing to say that if you live in the US or Canada you may be able to see the Aurora Borealis tonight! We saw small glimmers of it in southwest Virginia last night! But apparently it was seen in over 30 states and Canada. Please be sure to check your local weather and news to see if you can see it!
As for astrology, to my knowledge, we don't have a current ascribed meaning to it in western astrology. But the myths behind it are cool!
