File:20+ Flares with Rapid Obs. and Long Short Composites -Hinode XRT-.webm
For much of May and June, XRT was experimenting with a new observing program for flares that used a rapid succession of long and short exposure pairs. Such pairs, regularly used during XRT's synoptic observations, allow us to simultaneously see bright and faint structures by replacing saturated pixels in the long exposure with unsaturated data from the short exposure. You'll notice the extended "diamond" shapes surrounding the flare cores, which are due to an artifact known as CCD blooming, whereby saturation in the long exposure spills out into adjacent pixels. The linked movie shows all of the over 20 flare responses to use this program, which includes some 17 C- and 5 M-flares, most of which coming from Active Region 11476 between the 7th and 14th of May.
