Fermi/GBM detector 4 (top), Solar Orbiter/STIX (middle) count rates, and Ondřejov radio flux at selected frequencies (bottom) as a function of time during the 2 April 2022 eruption. Selected radio bursts are numbered (Figs. 3–6 and Table 1). Four grey time intervals, I-IV (Table 2), denote the STIX X-ray time intervals analysed in detail. All data are presented with respect to the time of the event detection on Earth orbit. Missing radio data at the beginning of the event were not archived because no radio bursts were observed at this time.
