Flaring active region observed by FSI and HRI_EUV during the Solar Orbiter flare campaign on 2024-03-23 in log scale. The image on the right highlights the FOV of HRI_EUV and the green box denotes the region of interest within the FOV of HRI that is studied in this work. The HRI_EUV frame shows a normal exposure observation of the flare at the non-thermal peak time (23:41:14 UT). During the M2.5 GOES-class flare, the two bright flare ribbons were saturated in the normal exposure frames.
