It was a bit of a battle with cloud this evening at my location, but the following images captured between 23:00 and 23:30 show what I managed to see in between the clouds. By 23:30 it had clouded over almost completely, just revealing tiny areas of green aurora glow in the gaps.
Image 5. 23:30 UTC. Taken at: ISO = 1600, f/2.8 @ 14 mm, exposure = 19 sec. Looking north. The end of my watching, as the cloud covered almost the entire sky apart from some tiny gaps over the mountain!
