Last night was a very good night for sky watching the southern aurora glowed with brilliance and delivered many changes in the two or so hours we could stand, gaze and tolerate the cold. Within an hour a thick fog had descended to treetop height and the temperature dropped further. Compared to the last solar storm in May the colour was visible much higher in sky and the colour seemed to streak both vertically and at a lower angles. I used an OM systems EM5 with the pro zoom the RAW files were processed in DXO pure raw, finished in Affinity Photos 2 and sharpened in NIK.
