The refined BAT ground \nposition is (RA,Dec) = 5.789, -5.602 {00:23:09,-05:36:08} [deg; J2000]\n+-2.3 arcmin, (radius, sys+stat, 90% containment).  The partial coding \nwas 12%.  \n\nThe light curve shows a broad peak from T+15 to T+65 and a second peak \nfrom T+80 to T+110.  There is no extended emission T>120 sec.  \nT90 (15-350 keV) is (80 +- 10) sec (estimated error including systematics).  \n\nThe power law index of the time-averaged spectrum is 1.89 +- 0.23.  \nThe fluence in the 15-150 keV band is (1.8 +- 0.3) x 10^-6 erg/cm2.  \nThe 1-sec peak photon flux measured from T0+98 sec in the 15-150 keV \nband is (1.1 +- 0.4) ph/cm2/sec.  All the quoted errors are at the 90% \nconfidence level.",
