Whenever I am north, I always check two things: what is the geomagnetic activity and is the sky dark and clear?
We were in Scotland last week visiting our son and travelled to Inverness to see the sights up there. We scouted out a good aurora viewing spot (on the 5th floor of a parking garage) just in case. The sky was clear. I knew the geomagnetic activity would need to be at least kp 5 to have a chance of seeing anything, especially from the city. I set my alarm for 3 AM because that was when the predictions said we might have enough activity. I checked the aurora web site and saw this:

Geomagnetic activity above kp 6! A G2 geomagnetic storm!
It was cold, but we went outside. It looked like there was a green glow around the moon.
I had my tiny travel tripod, and it did not reach high enough to see the horizon over the parking garage walls. But there was a handy grit container that I could put the tripod over to see over the wall.
I had read that unless you are very far north, the lights are not overhead but on the horizon, so I aimed my camera at the northern horizon.
Originally, the light was dim, but then it got brighter and it was green and it moved! What a treat! Then it went away, and it was time to get out of the cold and get a little more sleep before our tour in the morning.
Unfortunately, we did not get to see the Northern Lights again on this trip. I hope to see them again sometime in the future!
