On LIGO trigger time (T0= 2017-02-17 06:05:55.050 UT) the GRID\nexposure covered about 35% of the LIGO localization region that was observed\nwith off-axis angles between 10 and 70 deg.\n\nAn analysis of the data in the energy range 30 MeV - 10 GeV was performed on\ntimescales from 2 to 100 sec centered at T0. Preliminary values of 3-sigma\nupper limits obtained within the accessible G274296 localization region are\nreported below:\n\n1.3e-06 erg cm^-2 s^-1 for integration time of 2s,\n3.0e-08 erg cm^-2 s^-1 for integration time of 100s.\n\nThese measurements were obtained with AGILE observing a large portion of the\nsky in spinning mode. Additional analysis of AGILE data is in progress.",
