The aurora was already showing strongly when I arrived at site just after midnight. Image 1 below was taken at 00:21 UTC and looking in a south/south-east direction, showing a band of aurora with rays (purple ray tops visible on camera but only green could be seen to the eye).
This was one of the unusual nights where the band of aurora remained pretty much in the same location for quite a long time. Image 2 was taken almost 30 minutes after Image 1 and the aurora is still in much the same area. However, a minute later the aurora began to shift northward and passed directly overhead of my location (Image 3) before expanding to cover more sky but at lower intensity (Image 4). The auroral band was mostly entirely northwards of my location by 01:02 (Image 5). Almost immediately it shifted south again, came back overhead and resumed its previous location to the south with some active bands of moving rays (Image 6).
At 01:16 the auroral band grew in intensity and turned northwards again with a curve and began to shift location to come back directly overhead of me (Images 7 and 8). After this time the band quickly expanded and dissipated to cover a wider area of sky but at lower intensity (Image 9). By 01:24 the aurora was all north of my location and with several wide diffuse bands spread out over the northern half of the sky (Image 10). It remained like this for another 20 min until I left the site.
