Thanks...I used two lenses...a 25mm f1.4 and a 7.5mm 3.5. Both of which I was using wide open. I'll post a 25mm shot later tonight after I edit them. Obviously the exposure time was a fine balance between my aperture and ISO. I tried to keep the ISO as low as possible as with m4/3 it can get quite noisy above 800 ISO. That said I found anywhere from 30-60 seconds worked the best...it just depended on how busy the aurora was at that given moment. I probably should have used the live bulb feature (to get live, realtime results), but I was being lazy and didn't feel like connecting with wifi or with a remote (you need to press the shutter to start and stop the exposure).
A red flashlight would have been more handy than my iphone screen.

Beautiful images, I would love to be able to get shots of the northern lights someday. Have you tried using the 'Live Composition' mode on the E-M1. It would work well in situations like this and you probably could have gotten away with using a lower ISO.
I'm headed out tonight again. I couldn't figure out the initial photo setting when initializing live composite. I now know how to do it and if they are active as they were a week or so ago it should make for an interesting composition.
