GRB 220624A: AGILE detection

The AGILE satellite detected the long GRB 220624A at T0 = 2022-06-24 02:58:35 s (UTC), reported by Fermi GBM (GCN #32256). The burst is clearly visible in the AGILE scientific ratemeters of the SuperAGILE (SA; 20-60 keV), MiniCALorimeter (MCAL; 0.4-100 MeV), and AntiCoincidence (AC; 50-200 keV) detectors. The event lasted about 57 s and it released a total number of 5930 counts in the SA detector (above a background rate of 70 Hz), 88920 counts in the MCAL detector (above a background rate of 1135 Hz), and 212145 counts in the AC detector (above a background rate of 3195 Hz).

The event also triggered a partial high time resolution MCAL data acquisition, from T1 = 2022-06-24 02:58:34.36 s (UTC) to T2 = 2022-06-24 02:58:46.85 s (UTC), and released 14630 counts in the detector, above a background rate of 620 Hz. The MCAL light curve can be found at http://www.agilescienceapp.it/notices/GRB220624A_078864_583124315.000000.png . At the T0, the event was 20 deg off-axis. Additional analysis of AGILE data is in progress. Automatic MCAL GRB alert Notices can be found at: https://gcn.gsfc.nasa.gov/agile_mcal.html...
