Tempesta (TeleSpazio),\nreport on behalf of the AGILE Team:\n\nThe AGILE satellite detected the short GRB 2300308A at\nT0 = 2023-03-08 13:32:27.400 (UTC), reported by Fermi/GBM (GCN #33420) and\nBALROG (GCN #33421).\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, ACLat, 80-200 keV).\nThe event lasted about 1 s and it released a total number of 1166 counts\nin the MCAL detector (above a background rate of 576 Hz), and 7526 counts\nin the AC Top detector (above a background rate of 3445 Hz).\nThe AGILE ratemeters light curves can be found at:\nhttp://www.agilescienceapp.it/notices/GRB230308A_AGILE_RM_ND.png .\n\nThe event also triggered a high-time resolution MCAL data acquisition,\nfrom T0 to T0+12 s (UTC), and released 1484 counts in the detector,\nabove a background rate of 590 Hz. The MCAL light curve can be found at:\nhttp://www.agilescienceapp.it/notices/GRB230308A_082579_605367147.400000.png\n.\n\nAt the T0 the event was 133 deg off-axis. Additional analysis of AGILE data\nis in progress. Automatic MCAL GRB alert Notices can be found at:\nhttps://gcn.gsfc.nasa.gov/agile_mcal.html",
