Scientific paper

Following the bright outburst from the FSRQ 3C 454.3 detected by AGILE (ATel #3034), we report time-resolved detail of the detection of this flare by the Large Area Telescope (LAT), one of the two instruments on the Fermi Gamma-ray Space Telescope. Preliminary analysis from 2011-11-16:12:00:00 to 2011-11-17:06:00:00, indicates that the source flux increased by a factor of 4 in 12 hours from a flux of (14 +/- 2)x10-6 photons cm-2 s-1 to (56 +/- 4)x10-6 photons cm-2 s-1 (E>100 MeV, where errors are statistical only).
