Aurora Borealis
There was good Auroral activity after a CME event earlier in the week and with the Kp around 4 most of the evening I went out to Midmar. On arrival the stars were shining brightly and a bright green arc of Aurora stood prominently in the north, only a few degrees above the horizon. It slowly faded during the 30 minutes I observed but the camera picked up some details, including beams. Also observed were Orion and the winter constellations as well as the winter Milky Way.
