Chromospheric response and magnetograms. AIA 1600 Å images (panels a, b), difference image between them (d) and HMI LOS magnetogram (c) for the November 10, 2022 flare. Green contours show the STIX image in the 16−28 keV energy range, red in 4−8 keV (30, 60, and 90% of the maximum intensity). The HMI image is scaled from −1000 to +1000 G. Blue contours in the HMI image show the areas used for the calculation of the mean magnetic flux densities. The purple contour indicates the area from the AIA 1600 Å base difference image considered to be part of a separate, smaller loop system. Units are given in arcseconds. Integration times are 17:14:05−17:15:25 UT for the nonthermal and 17:15:25−17:17:25 UT for the thermal image respectively.
