Baker's Dozen of Flares
February 6, 2014
A busy active region just rotating into view offered up about 13 flares in just two and a half days (Jan. 27-29, 2014). Five of them were of the M-Class (Medium) flares and the rest were smaller. The video clip, taken in extreme ultraviolet light at a cadence of an image every eight minutes, shows ionized iron at about 10 million degrees K. The still of an M-class flare was taken at 19:39 UT on Jan. 28. The brightness of the flare causes very bright saturation and 'blooming' above and below the flare region on the CCD detector and caused extended diffraction patterns to spread out across the SDO imager.
