Tempesta (TeleSpazio), report on behalf of the AGILE\nTeam:\n\nThe AGILE satellite detected the long GRB 220307B at\nT0 = 2023-02-07 04:40:48 s (UTC) (CALET trig. 1359779945).\n\nThe burst is clearly visible in the AGILE scientific ratemeters of the\nMiniCALorimeter (MCAL; 0.4-100 MeV) and in all the five panels of the\nAntiCoincidence\nsystem (AC Top, 50-200 keV; AC Lat, 80-200 keV). The event lasted about 14\ns and it\nreleased a total number of 15515 counts in the MCAL detector (above a\nbackground rate of 996 Hz),\nand 49298 counts in the AC Top detector (above a background rate of 2674\nHz).\nThe AGILE ratemeters light curves can be found at\nhttp://www.agilescienceapp.it/notices/GRB230207B_AGILE_RM_ND.png .\n\nThe event also triggered a (partial) high-time resolution MCAL data\nacquisition,\nfrom T0-1 s to T0+5 s (UTC), and released 116 counts in the detector, above\na background rate of 67 Hz. The MCAL light curve can be found\nat\nhttp://www.agilescienceapp.it/notices/GRB230207B_082154_602829648.000000.png\n.\n\nAdditional analysis of AGILE data is in progress.
