Set of 171 Å images taken from TRACE (171 Å) for different moments during the evolution of SOL1999-10-22T09:16 event. Locations of brightenings are circled in every image. In the top-left image all regions are marked by letters. In selected images reconstructed HXR contours are marked for HXT L (dashed line) and M1 (solid line) for 30, 50, 70, and 90% of maximum brightness. See the electronic form for a color version of the plot and for a movie presenting the entire event.
