Giuliani (INAF/IASF-Mi), report on behalf of the AGILE Team:\n\nThe AGILE Mini-CALorimeter (MCAL) detected a burst at T0 = 2021-12-06\n19:51:10.80 +/- 0.01 s (UTC). The event lasted about 4.5 s and released a\ntotal number of ~3374 counts in the detector (in the 0.4-100 MeV energy\nrange), above an average background rate of 599 Hz. The MCAL light curve\nshows two main peaks and can be found at\nhttp://www.agilescienceapp.it/notices/075998_GRB_MCAL_565905070.805285.png\n\nThe burst is also clearly visible in the AGILE scientific ratemeters of the\nSuperAGILE (SA; 20-60 keV), MiniCALorimeter (MCAL; 0.4-100 MeV), and\nAntiCoincidence (AC; 50-200 keV) detectors. The event lasted about 5 s and\nit released a total number of 853 counts in the SA detector (above a\nbackground rate of 90 Hz), 8286 counts in the MCAL detector (above a\nbackground rate of 1260 Hz), and 18890 counts in the AC detector (above a\nbackground rate of 3600 Hz). The AGILE ratemeter light curves can be found\nat http://www.agilescienceapp.it/notices/GRB211206A_AGILE_RM.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.",
