Symphony

The aurora has been going nuts lately (or so the alerts on my phone seem to tell me) but it's been pretty foggy/cloudy where I'm at. Anyway, here's another from the other night. I haven't seen this much colour in an aurora before - usually they're just a greenish colour. The moon had gone behind a thin cloud briefly for this shot, so about 4 of the shots I took were a bit underexposed. I'd love to get 2.8 glass for this sort of thing!
Location: Eagle Bay, BC, Canada

Thanks for looking!
