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 2.1e-07 to 2.1e-06 erg cm^-2 s^-1, with exposure of about 65% of the\nLR over the time interval (T0 - 100 s ; T0 s);\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.",
