Sept. 6th was the strongest solar activity in 12 years (ref. NASA/NOAA). Two days later the solar storm reached the earth and caused strong Aurora VHF DX and a collapse of the shortwave bands. I was lucky to be in the polar Region during that time, making this 3 mins Video about the Northern Lights.
