STIX images showing 4−1 keV (thermal; purple), 11−16 keV (intermediate; blue), and 16−28 keV (nonthermal; green) contours at the 50%, 70%, and 90% levels, each integrated over a two-minute period centered around a peak in the STIX 16−28 keV energy band (cf. Fig. 7b). The STIX images were generated using the maximum entropy method MEM_GE (Massa et al. 2020) with an AIA 171 Å base selected from around the mean time of the image. Units are arcseconds within the Solar Orbiter view. The AIA images have been rotated to the Solar Orbiter viewpoint.
