The GRID large-FoV covered about 25-35% of the LR on\nintegrations\nfrom about T0-100s to T0, and from T0+300s to T0+400s following the T0,\nwith\noff-axis angles between 20 and 70 deg, approximately.\n\nAn analysis of the GRID data in the energy range 50 MeV - 10 GeV was\nperformed on timescales from 2 to 100 sec centered at T0-50s. Preliminary\nminimum and maximum values of 3-sigma upper limits obtained within the\naccessible G284239 LR are reported below:\nfrom 1.4e-07 erg cm^-2 s^-1 to 6.5e-07 erg cm^-2 s^-1 for an integration\ntime\nof 20s, and from 3.2e-08 erg cm^-2 s^-1 to 2.5e-07 erg cm^-2 s^-1 for an\nintegration 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.",
