Description:

22 Aug 2014 1540 UTC AR2146 C6.2 flare.

The flare is the very bright white spots above bottom, right of center.

This is the processed image that I have that is closest to the peak of the flare. See 201408221540UTCFlare gif for animation.

Converted to color from greyscale.

North is up to the left of center.
