The spacecraft did not autonomously slew\nto the burst since automated slewing was not yet enabled.\n\nThe BAT ground-calculated location is RA,Dec 100.183,-37.066 (J2000)\nwith an uncertainty of 7 arcmin (radius, 3-sigma, including systematic\nuncertainty using a preliminary bore-sight alignment calibration).\nThis is 27 degrees off the BAT bore sight and was in the partially encoded\nfield of view.\n\nThe burst lightcurve is multi-peaked with structure within the peaks\nwith the main emission lasting ~60 sec.  The peak flux was 7.5 events/cm^2/sec\n(1-sec sampling; unsaturated; ~15 to 100 keV; ~28 Crab).\nThe total duration was ~130 sec.  The fluence was ~2e-5erg/cm^2.\nA reduced energy band is being quoted because of our response uncertainty\nin the >100 keV band, and because of strong emission by this burst \nin this band.",
