Trieste, and INFN Trieste), report on\nbehalf of the AGILE Team:\n\nIn response to the LIGO-Virgo GW event S200112r at T0 = 2020-01-12\n15:58:38.094 UTC a preliminary analysis of the AGILE exposure at T0 shows\nthat the Gamma-Ray Imaging Detector (GRID) exposure covered the 28% of the\n90% c.l. localization region (LR) (11% of the LR is occulted by Earth).\n\nWe performed an analysis of the GRID data in the energy range 50 MeV - 10\nGeV on T0, where good exposure of the S200112r 90% c.l. LR was available.\n\nNo candidate gamma-ray transient was detected.\n\nThe following preliminary GRID values of 3-sigma upper limit (UL) are\nobtained:\n\nfrom 7.4e-07 to 6e-06 erg cm^-2 s^-1, with exposure of about 28% of the LR\nover the time interval ( T0 -2s ; T0 + 2s );\nfrom 3.0e-07 to 9.1e-06 erg cm^-2 s^-1, with exposure of about 27% of the LR\nover the time interval ( T0s ; T0 + 10s );\nfrom 7.7e-08 to 1e-05 erg cm^-2 s^-1, with exposure of about 36% of the LR\nover the time interval ( T0s ; T0 + 100s );\n\nThese measurements were obtained with AGILE observing a large portion of\nthe sky in spinning mode. Additional analysis of AGILE data is in progress.",
