TITLE: GCN CIRCULAR NUMBER: 31975 SUBJECT: GRB 220430A: AGILE detection DATE: 22/04/30 19:06:05 GMT FROM: Alessandro Ursi at INAF/IAPS A. Ursi (INAF/IAPS), F. Longo (Univ.

Giuliani (INAF/IASF-Mi), report on behalf of the AGILE Team: The AGILE satellite detected the GRB 220430A at T0 = 2022-04-30 13:53:45 (UTC), reported by Swift (GCNs #31972 and #31973). The burst is clearly visible in the AGILE scientific ratemeters of the SuperAGILE detector (SA; 20-60 keV) and in all the five panels of the AntiCoincidence system (AC Top, 50-200 keV; AC Lat, 80-200 keV). The event lasted about 25 s and it released a total number of 2685 counts in the SA detector (above a background rate of 100 Hz), 25765 counts in the MCAL detector (above a background rate of 1070 Hz), and 67565 counts in the AC detector (above a background rate of 2710 Hz). The AGILE ratemeter light curves can be found at http://www.agilescienceapp.it/notices/GRB220430A_AGILE_RM.png . As pointed out in GCN #31972, we notice that this event took place at the end of an intense X-class solar flare, clearly detected by all the AGILE scientific ratemeters. A more extended light curve can be found at http://www.agilescienceapp.it/notices/GRB220430A_AGILE_RM_all.png . Additional analysis of AGILE data is in progress.
