Multiwavelength light curves of the flare of September 29, 2022. Top panel: Combined dynamic radio spectrum from ORFEES (144–1004 MHz), e-CALLISTO (81–144 MHz), NDA (13.9–80 MHz), and WAVES/RAD2 (1.1–13.8 MHz) showing a complex group of fast-drifting bursts with clear indications of repeated episodes of electron acceleration during the peak of the STIX and Fermi LAT and GBM emission. Middle panel: ORFEES normalized flux density at three frequencies (789.5, 898.5, and 998.5 MHz). Bottom panel: Fermi LAT > 100 MeV flux points (red markers), normalized STIX and GBM time profiles in the 32–76 keV energy range are shown in blue and green solid lines, respectively. The Sun left the Fermi LAT field of view at 12:01 UT.
