Giuliani (INAF/IASF-Mi), report on behalf of the AGILE Team:\n\nThe AGILE satellite detected the GRB 221022B at T0 = 2022-10-22 22:56:11.76\n+/- 0.01 s (UTC), reported by Fermi GBM (#GCN 32820, trigger no. 688172153).\n\nThe burst is clearly visible in the AGILE scientific ratemeters of the\nMiniCALorimeter (MCAL; 0.4-100 MeV), and AntiCoincidence (AC; 50-200 keV)\ndetectors. The event lasted about 15 s and it released a total number of\n27380 counts in the MCAL detector (above a background rate of 1070 Hz), and\n80780 counts in the AC detector (above a background rate of 2760 Hz). The\nAGILE ratemeter light curves can be found at\nhttp://www.agilescienceapp.it/notices/GRB221022B_AGILE_RM.png .\n\nThe event also triggered a partial high time resolution MCAL data\nacquisition, covering the onset of the first episode, from T0-33.15 s to\nT0+1.70 s, and released a total number of ~830 counts in the detector,\nabove an average background rate of 588 Hz. The MCAL light curve can be\nfound at\nhttp://www.agilescienceapp.it/notices/080607_GRB_MCAL_593564171.767936.png .\n\nThe AGILE-MCAL detector is a CsI detector with a 4 pi FoV, sensitive in the\nenergy range 0.4-100 MeV. Additional analysis of AGILE data is in progress.\nAutomatic MCAL GRB alert Notices can be found at:\nhttps://gcn.gsfc.nasa.gov/agile_mcal.html.",
