An aurora was apparent on my test photo facing northwards at 21:50 UTC, and probably had been visible for a while but was difficult to see by eye due to the bright light from the full moon! I didn’t go out until 22:40, by which time there were a couple of weak bands of aurora low across the northern horizon (Image 1). The moonlight was so bright that the scenery appeared like daylight even relatively short exposures of only 4 or 5 seconds. The aurora kept slowly strengthening and weakening again over the following 30 min (Images 2 and 3), but in the moonlight then it never appeared too well-defined. After 23:15 the band thickened and became more vibrant to the eye, but was still relatively low in the sky (Images 4 and 5). It stayed similar in form until we left to go home at 23:40.
