We downloaded all reconstructed data products available in JSOC and investigated the respective movies. The flare ribbons are well visible in $I_{\rm c}$, their visibility is enhanced when instead of $I_{\rm c}$ a running difference (the difference between consecutive frames) is displayed. An example of one frame is shown in Fig. \[fig:X54-context\]. Similar
