Severe geomagnetic storm

A strong CME has hit the Earth, according to Spaceweather.com. The storm has caused severe geomagnetic storm around the globe, thus it means also aurora borealis! That was the case also here in Puolanka, where I tried to make observation of the supernova SN2011fe in Messier 101 yesterday evening. When I arrived to my observing site, I noticed that the sky was very light and full of magnificent aurora borealis!

There were also some high clouds in the sky (because of the rain front that was approaching this part of the country), and the aurora and the clouds together made observing very difficult. I tried to locate the supernova, but I just couldn’t do it because of poor observing conditions. So it means that I wasn’t able to do any observations last night.

Anyway, here’s the summary from last night: Summary of obs session #12/11-12
