LR was available.\n\nNo candidate gamma-ray transient was detected.\n\nThe following preliminary GRID values of 3-sigma upper limit (UL) are\nobtained:\n\nfrom 1.2e-07 to 3.6e-07 erg cm^-2 s^-1, with exposure of about 34% of the\nLR over the time interval ( T0 - 200s ; T0 - 100s );\nfrom 3.9e-08 to 8.7e-06 erg cm^-2 s^-1, with exposure of about 32% of the\nLR over the time interval ( T0 + 200s ; T0 + 300s ).\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.",
