Left: RHESSI images at 12−25 keV (green), with contours at 12−25 keV (green) and 50−100 keV (yellow) overlaid on the images. Right: RHESSI images at 25−50 keV (blue), with contours at 25−50 keV (blue) and 50−100 keV (yellow) overlaid on the images. Images and contours are shown for five time intervals integrated over 16 s (from top to bottom: 01:49:00−01:49:16, 01:51:00−01:51:16, 01:52:42−01:52:58, 01:55:02−01:55:18, and 01:55:22−01:55:38 UT) corresponding to peaks in the 50−100 keV range. Images are obtained using detectors 2F, 3F, 4F, 5F, 6F, 7F, 8F, and 9F and the CLEAN algorithm. The green, blue, and yellow contours are 60%, 70%, 80%, and 90% of the image maximum value.
