Ursi (INAF/IAPS),\nF.Lucarelli, C. Pittori, F. Verrecchia (SSDC, and INAF/OAR),\nA.Bulgarelli, V. Fioretti, N. Parmiggiani (INAF/OAS-Bologna),\nreport on behalf of the AGILE Team:\n\nIn response to the LIGO/Virgo GW event S191222n at T0 = 2019-12-22\n03:35:37.119 (UT), a preliminary analysis of the AGILE minicalorimeter\n(MCAL) triggered data found no event  candidates within a time\ninterval covering -/+ 15 sec from the LIGO/Virgo T0.\n\nAt the T0, about 60% of the S191222n 90% c.l. localization region was\naccessible to the AGILE MCAL.Three-sigma upper limits (ULs) are\nobtained for a 1 s integration time at different celestial positions\nwithin the accessible S191222n localization region, from a minimum of\n1.4E-06 erg cm^-2 to a maximum of 6.5E-06 erg cm^-2 (assuming as\nspectral model a single power law with photon index 1.5).\n\nThe AGILE-MCAL detector is a CsI detector with a 4 pi FoV, sensitive\nin the energy range 0.4-100 MeV. Additional analysis of AGILE data is\nin progress."
