Thx guys.
Derek, it's one of the rewards for living in a colder, wetter climate, along with the fact that the whole state is virtually a dark sky site :-)
Brad these weren't very visual. I have seen the sky dancing in reds and whites however at other times.
These were 30sec at f4 ISO800 during a Kp4 event. If it goes over that to 5 then it gets visual.
