LR was available.\r\n\r\nNo candidate gamma-ray transient was detected.\r\n\r\nThe following preliminary GRID values of 3-sigma upper limit (UL) are obtained:\r\n\r\nfrom 5.9e-08 to 5.5e-06 erg cm^-2 s^-1, with exposure of about 42% of the LR\r\nover the time interval ( T0 -200s ; T0 -100s ).\r\n\r\nThese measurements were obtained with AGILE observing a large portion of\r\nthe sky in spinning mode. Additional analysis of AGILE data is in progress.",
