Longo (Univ.\nTrieste, and INFN Trieste), report on behalf of the AGILE Team:\n\nIn response to the LIGO-Virgo GW event S200219ac at T0 = 2020-02-19\n09:44:15.195 UTC a preliminary analysis of the AGILE exposure at T0 shows\nthat the Gamma-Ray Imaging Detector (GRID) exposure covered less than 10% of\nthe 90% c.l. localization region (LR; 40% of the LR is occulted by Earth).\n\nWe performed an analysis of the GRID data in the energy range 50 MeV - 10\nGeV at T0, where good exposure of the S200219ac 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 1.7e-06 to 9.6e-06 erg cm^-2 s^-1, with exposure of about 14% of the LR\nover the time interval (T0 s ; T0 + 10 s);\nfrom 3.8e-08 to 2.0e-06 erg cm^-2 s^-1, with exposure of about 48% of the LR\nover the time interval (T0 s ; T0 + 100 s);\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.",
