There was a very strong geomagnetic storm in progress this evening, and as a consequence the aurora was visible even in the twilight at dusk and before it was fully dark (Images 1 to 5: high in the sky to the north). The aurora quickly moved directly overhead in a narrow band (Images 6 and 7), and then started to move south of my location (Images 8 to 10). Although much of the aurora was south, two strong bands were visible east to west across the sky directly overhead (Image 11). However, by this point I was losing the battle with the cloud and headed home. The aurora continued to be active for much of the rest of the night.
