Snapshots of coronal loop expansion in STEREO-A/EUVI 195 Å base difference images for the event on September 6, 2011. The time steps are: (a) maximum dimming extent, (b) appearance of post-flare arcade and faint loops, (c) further expansion of loops into the higher corona, and (d) just before the second flare. The full temporal evolution is available in the accompanying video created in JHelioviewer (Müller et al. 2017).
