It was a clear sky this evening, and as I was walking my dog away from my house I didn’t notice anything in the northern sky. On my way back I stopped by one of my neighbors.

I asked Bjørn Tore for his camera so I could take a shot to verify. It was definitely green! I immediately ran home to set up my gear before it all faded.

This shot is one of a few other nice exposures. Unfortunately the clouds came in rather quickly. Just after 100 exposures the sky was more or less covered, and that is merely a 4 second timelapse.
