The ground-analysis position is\nRA,Dec 358.757, +24.874 (J2000) with an uncertainty of 2 arcmin\n(radius, 90%, stat+sys).  This is 50 arcseconds from the XRT ground-\ncalculated position reported by Kennea et al. in GCN Circ. 3827.\n\nThe light curve shows a long weak peak with indistinct structure from\nT-12 to T+37 seconds.  T90 is 36 +/- 4 sec.  Fitting a simple power\nlaw over the interval from T-2 to T+34 sec, the photon index is\n2.6 +/- 0.3 with a fluence of 4.2 +/- 0.8 x 10^-7 erg/cm^2 in the\n15-350 keV band (90% c.l.).  The peak flux in a 1-sec wide window\nstarting at T+9.5 seconds is 0.46 +/- 0.14 ph/cm^2/sec (15-350 keV).",
