Wilson-Hodge (NASA/MSFC)report:\n\n\"At 13:10:12 UT on 10 August 2008, the GLAST Burst Monitor (GBM) \ntriggered and located GRB 080810 (GBM 080810.549, trigger 240066613), \nwhich was also detected by Swift (Page et al., GCN 8080). \nThe on-ground calculated location, using the GBM trigger data, is\nRA, Dec 357.18, -4.61 which is equivalent to\n    RA(J2000) = 23h 49m\n    Dec(J2000) = -4d 37'\nwith an uncertainty of 5.0 degrees (radius, 1-sigma containment, \nstatistical only). The angle from the Large Area Telescope (LAT) \nboresight is 61 degrees.\n\nThe GBM light curve shows a slow rise starting at T0-20, followed by \na main emission phase comprising 5 pulses, a quiescent period and a \nsixth pulse at T0+102 s. \n\nThe time-averaged spectrum from T-0.5 to T+53.1 sec is best fit by a \npower law function with an exponential high energy cutoff. The cutoff \nenergy is 313.5 +/-73.6 keV and the power law index is -0.91 +/-0.12, \nwith a reduced chi-square of 1.1 for 226 degrees of freedom. \n\nThe fluence in the 50-300 keV band is (6.9 +/- 0.5) x 10^-6 erg/cm2. \nThe 1-sec photon flux measured from T+23.5 sec in the 50-300 keV band \nis 1.85 +/- 0.16 ph/cm2/sec. All the quoted errors are at the 90% \nconfidence level.\"",
