Also, much of Minnesota, including Minneapolis/St. Paul, will have prime viewing too! Anyone that lives up there should go out at around 12-2AM tonight.
THIS IS SO EXCITING!!!
I haven't been paying attention to solar activity until recently, but I get the impression that a G4 storm is kind of a big deal that doesn't happen that often. That one is happening on a Friday night is even less likely. This is probably your best chance at seeing aurora short of traveling above the Arctic Circle.
