What a fantastic aurora shot! Of course one would think of a flag or curtain, but I'm also struck, for the first time ever on viewing an aurora photo, of the relationship to a rainbow! Although the source of the phenomenon is so totally different, one can definitely see a progression here from purple to red to green, and even at the bottom left, I see a touch of orange.
And here's a crazy question. Has anyone (okay, a group project, unless it's from space) ever observed auroras at both poles simultaneously? Is there any correlation? I would expect a positive correlation as a first guess, just in that we see more auroras when Sol is more active, and I don't see how that would strictly prefer on pole at a time.
