TRACE 195 Å EUV direct images (in reverse color-scale, where dark corresponds to high intensities) of the source M2.1 flare in event 2 around the flare maximum (panel a) and ten minutes later (panel b). The red rectangles depict the CDS FOV. White rectangles mark pixels with enhanced line broadenings. Panel a shows the EIT flare in Fig. 1b at higher resolution. The noise spikes in the images are not filtered out.
