Saw the auroras at 42 north amazingly enough last night. If one didn't know what they were looking for they'd never known they were there. With a camera it makes it easy to be sure. For a couple hours an F1.8 fast lens and 3200 ISO was readily picking up the red/purple higher up while the near horizon area was full of clouds. Got a gap and could see green through it and was then sure.
About a 5 minute period around 11:30 central time you could see they were a good bit lighter and barely make out there was pillaring going on above. Take a shot and you could really see the pillars. Trick was that really high iso to limit the shutter/beam movement. Pretty crazy though given location and the fact the Bz wasn't even south for a lot of this. But visually obviously this was nothing crazy. But cool to see mixed with a very clear Milky Way and a slew of shooting stars. Most I've seen in a night in a long time.
Also if one looks close at the bottom you can see a storm flashing away. If only that band of clouds had been gone, a telephoto of that would have been cool with the green of the auroras.
For those that think they aren't far enough north, you may as well take the camera out and see what it thinks, given any storming. I would have never expected to see or pick them up with a 0 or positive Bz, from here. I knew even before I could see where the green was that I was seeing lighter sky above that cloud band, early on.
Camera was a canon 5D II, cheap 50mm F1.8 lens doing wonders.
