Pilia\n(INAF/OA-Cagliari) report on behalf of the AGILE Team:\n\nIn response to the LIGO/Virgo GW event S191204r at T0 = 2019-12-04\n17:15:26.092 (UT), a preliminary analysis of the AGILE minicalorimeter\n(MCAL) triggered data found no event candidates within a time interval\ncovering -/+ 15 sec from the LIGO/Virgo T0.\n\nAt the T0, about 80% of the S191204r 90% c.l. localization region was\naccessible to the AGILE-MCAL.Three-sigma upper limits (ULs) are obtained\nfor a 1 s integration time at different celestial positions within the\naccessible S191204r localization region, from a minimum of 2.0E-06 erg\ncm^-2 to a maximum of 3.0E-06 erg cm^-2 (assuming as spectral model a\nsingle power law with photon index 1.5).\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.",
