Description:

A M7 class flare occurred at 02 Oct 2014 1915 UTC approx 2 minutes after I took this. Talk about bad timing this time. The flare was in the AR12172-12173 region, the bright white region at the bottom of the Sun.

The laptop got to hot, was acting badly, so I shut everything down immediately after I took the video that became this image. Brought the laptop inside and put a fan on it. An hour later I was finally able to turn it on again after several attempts.
