12 hours in about 50 seconds. Exposure was 30s at f4 and ISO 6400 for the night part with 35s intervals (5s between shots). As the sun rose, I first changed ISO value, then aperture and when that wasn't enough, I changed exposure time.
I used a Nikon 5100. Changing batteries, ISO, aperture and exposure values were tricky as I had to restart the intervalometer each time. I used a chronometer when changing exposure value to make sure I wouldn't screw up the interval time.
There's a little hiccup when the clouds clear to reveal the auroras. I was doing this during a night shift at work and thought the battery could survive an extra 15 minutes. It didn't so there's 15 minutes missing, or about 1 second of video. Other problems during previous attempts were bumping into the tripod just before sunrise which triggered a long string of curse words, as well as one sequence of 5 or 6 shots that had unrecuperable overexposed areas, which messed up the night to day transition.
Getting the transition is pretty tricky and required quite a bit of processing. All this for seconds. But it was an awful lot of fun.
Here it is:

For those who wonder, the light at the beginning is from the moon. You can also see the pilot tried to get out of my shot at the end, but was too late... :p
