Tempesta (TeleSpazio),\nreport on behalf of the AGILE Team:\n\nThe AGILE satellite detected the long GRB 230307A at\nT0 = 2023-03-07 15:44:06 (UTC), reported by Fermi/GBM (GCN #33405 and\nGCN #33407), GECAM (GCN #33406) and Stix (GCN #33410).\n\nThe burst is clearly visible in the AGILE scientific ratemeters of the\nMiniCALorimeter (MCAL; 0.4-100 MeV), and in all the panels of the\nAntiCoincidence detectors (AC Top, 50-200 keV; AC Lat, 80-200 keV).\nThe event lasted about 30 s and it released a total number of 527069 counts\nin the MCAL detector (above a background rate of 1154 Hz), and 920952 counts\nin the AC Top detector (above a background rate of 2959 Hz).\nThe AGILE ratemeters light curves can be found at:\nhttp://www.agilescienceapp.it/notices/GRB230307A_AGILE_RM_ND.png .\n\nThe event also triggered a high-time resolution MCAL data acquisition,\nfrom T0 to T0+22 s (UTC), and released 241403 counts in the detector,\nabove a background rate of 510 Hz. The MCAL light curve can be found at:\nhttp://www.agilescienceapp.it/notices/GRB230307A_082567_605288646.000000.png\n.\n\nAt the T0, the event was 54 deg off-axis.\nAdditional analysis of AGILE data is in progress.\nAutomatic MCAL GRB alert Notices can be found at:\nhttps://gcn.gsfc.nasa.gov/agile_mcal.html",
