Bulgarelli, N. Parmiggiani (INAF/OAS-Bologna), M. Pilia (INAF/OA-Cagliari),\nF. Longo (Univ. Trieste, and INFN Trieste) report on behalf of the AGILE Team:\n\nIn response to the LIGO/Virgo GW trigger event S190408an at T0 = 2019-04-08 18:18:02 (UT)\n(GCN #24069) we performed a further analysis of the AGILE Gamma-Ray Imaging Detector\n(GRID) data after the trigger time.\n\nAn analysis of the data in the energy range 30 MeV - 10 GeV was performed over the time\ninterval T0+200s -- T0+300s, where full coverage of the majority of the localisation\nregion (>95%) was reached.\n\nPreliminary GRID values of 3-sigma upper limits (UL) obtained within the accessible\nLIGO/Virgo 90% c.l. localization region over this time interval are in the range:\n\nfrom 2.5e-07 to 3.5e-07 erg cm^-2 s^-1 for an integration time of 100s.\n\nThese UL values are compatible with those obtained for an integration time of 100s\nbefore T0, and reported in the previous AGILE GRID GCN #24071.\n\nThese measurements were obtained with AGILE observing a large portion of the sky\nin spinning mode.",
