You would think that living in Norway i would see this the whole time, but in honesty i have only seen it properly once, that was in October 2008, in Rondane. I was actually out looking for the meteor strom that was mean to be happening but ended up photographing this instead. This is a stack of 7 photos, a total exposure of 70s at 18mm/3.5 with a nikon D7000.
