Marisaldi (INAF/IASF-Bo and Bergen University),  A.\nGiuliani (INAF/IASF-Mi), report on behalf of the AGILE Team:\nIn response to the LIGO/Virgo GW trigger event G299232 at T0 = 2017-08-25\n13:13:37.983 UTC (GCN #21693), we performed an analysis of the AGILE\nGamma-Ray Imaging Detector (GRID) data on different  timescales. On LIGO/Virgo\ntrigger time (T0) the GRID exposure covered nearly 42% of the LIGO/Virgo\nlocalization region (at 90% confidence level; LR), observed at off-axis\nangles between 20 and 55 deg.\n\nAn analysis of the data in the energy range 50 MeV - 10 GeV was performed\non timescales from 2 to 100 sec centered at T0.\nPreliminary values of 3-sigma upper limits (ULs) obtained within the\naccessible LIGO/Virgo 3-sigma LR are reported below:\n\nfrom 1.5e-06 to 7.8e-06 erg cm^-2 s^-1 for integration time of 2s\nfrom 1.5e-07 to 7.8e-07 erg cm^-2 s^-1 for integration time of 20s\nfrom 3.9e-08 to 2.2e-07 erg cm^-2 s^-1 for integration time of 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.",
