On LIGO trigger time (T0), the GRID\nexposure covered about 40% of the LIGO localization region; this region\nwas observed with off-axis angles between 0 and 70 deg.\n\nAn analysis of the data in the energy range 30 MeV - 10 GeV was performed\non timescales from 2 to 1000 sec centered at T0.\nTypical 3-sigma preliminary upper limits (UL) obtained within the\naccessible G268556 localization region are reported below:\n\n2.0e-06 erg cm^-2 s^-1 for integration time of 2s,\n3.4e-08 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.\nAdditional GRID data analysis on longer time intervals is in progress.",
