McGlynn (MPE/Excellence Cluster) reports on behalf of the Fermi GBM Team:\n\n\"At 02:26:50.94 UT on 25 August 2011, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 110825A (trigger 335932012 / 110825102),\nwhich was also localised by the IPN\n(Hurley et al. 2011, GCN 12307).\n\nThe angle from the Fermi LAT boresight at trigger time was 65 degrees.\nApproximately 100 s from trigger time, the Fermi spacecraft executed\nan automatic maneuver in response to a command from GBM, in\norder to place the burst closer to the LAT boresight.\n\nThe GBM light curve shows a soft precursor (~2s) followed by 2 bright\npeaks from T0+10s to T0+25s, with a possible soft tail at T0+75 to\nT0+85s. The duration (t90) is 62.5 +/- 0.2 s (50-300 keV).\n\nThe time-averaged spectrum from T0-0.64 s to T0+82.3 s is\nbest fit by a Band function with Epeak = 233.6 (+21.9/-19.9) keV,\nalpha = -1.23 (+/-0.03), and beta = -2.04 (+0.06/-0.08)\n(C-Stat 719.72 for 490 d.o.f.).\n\nThe event fluence (10-1000 keV) in this time interval is\n(5.45 +/- 0.70)E-5 erg/cm^2. The 1 s peak photon flux measured\nstarting from T0+15.5 s in the 10-1000 keV band\nis 53.7 +/- 0.4 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
