Wilson-Hodge (NASA/MSFC)\nreports on behalf of the Fermi GBM Team:\n\n\"At 20:23:22.92 UT on 11 July 2009, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 090711 (trigger 269036604 / 090711850).\n\nThe on-ground calculated location, using the GBM trigger\ndata, is RA = 139.6, DEC = -64.7 (J2000 degrees,\nequivalent to 09 h 18 m, -64 d 42 '), with an uncertainty\nof 1 degrees (radius, 1-sigma containment,\nstatistical only; there is additionally a systematic\nerror which is currently estimated to be 2 to 3 degrees).\nThe angle from the Fermi LAT boresight is 13 degrees.\n\nThe GBM light curve consists of multiple peaks\nwith a duration of at least 100 s (8-1000 keV). The GBM detectors\nwere turned off for SAA entry about 83 seconds after the\ntrigger. The time-averaged spectrum from T0-20.992 s to T0+82.433 s is\nadequately fit by a power law function with an exponential\nhigh energy cutoff.  The power law index is 1.3 +/- 0.1 and\nthe cutoff energy, parameterized as Epeak, is 210 +/- 70  keV\n\nThe event fluence (8-1000 keV) in this time interval is\n(1.17 +/- 0.16 )E-05 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+1.536 s in the 8-1000 keV band\nis 4.2 +/- 0.6 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
