Overview of the 2022 May 4 M5.7–class flare as observed by multiple instruments. Panel a shows the GOES X-ray light curve of the flare. Panels b–g show the context SDO/AIA and SDO/HMI observations at 08:52:45 and 08:57:45 UT, denoted by vertical lines in panel a. Panel g includes the contours of the polarities (positive in red and negative in blue) from panel d. The FOVs of the HiFI+2 and IRIS/SJI instruments are indicated in panel f (only IRIS/SJI FOV in panel d), and the corresponding observations are shown in panels i–l, with the location of the IRIS slit indicated and the HiFI+ images resampled to the IRIS resolution and FOV. The red arrows in panels d and i point to the location of pixel No. 53. Ondřejov ground-based observations from the spectrographs FICUS and HSFA-2 and the SPS are shown in panels m–o, respectively. The black line in panel n indicates the HSFA-2 slit position. Animations of the AIA, IRIS, and GREGOR observations (panels e–l) are available online.
