AR2645 Class C Flare – 6th April 2017

AR2645 (right side of animation) plus large prominence (left side). AR 2645 flared at class C shortly after 12:00UTC, unfortunately whilst the camera was not capturing for the first part of this, but the tail end of the flare is captured as can be seen when the AR jumps in brightness about 2/3rds of the way through the animation.
