Giuliani (INAF/IASF-Mi), and P.\nTempesta (TeleSpazio), report on behalf of the AGILE Team:\n\nThe AGILE Mini-CALorimeter (MCAL) detected a burst at T0 = 2023-01-04\n06:03:15.00 +/- 0.01 s (UTC). The event lasted about 1.10 s and released a\ntotal number of 2073 counts in the MCAL detector (in the 0.4-100 MeV energy\nrange), above an average background rate of 594 Hz. The MCAL light curve\ncan be found at\nhttp://www.agilescienceapp.it/notices/GRB230104A_081663_599896995.000000.png\n.\n\nThe burst is also visible in the AGILE scientific ratemeters of the\nMiniCALorimeter (MCAL; 0.4-100 MeV), and AntiCoincidence (AC; 50-200 keV)\ndetectors, where it released a total number of 6525 counts in the MCAL\ndetector (above a background rate of 1200 Hz), and 13285 counts in the AC\ndetector (above a background rate of 3215 Hz). The AGILE ratemeters light\ncurves can be found at\nhttp://www.agilescienceapp.it/notices/GRB230104A_AGILE_RM_D.png .\n\nAdditional analysis of AGILE data is in progress.
