The refined BAT ground position\nis (RA,Dec) = 324.454, 55.798, [deg; J2000] +- 3 arcmin, (95%\ncontainment).  The partial coding was 98%.  \n\nThe light curve shows multiple peaks, with the main peak \nstarting about T+42 seconds after the trigger and with another\nhard peak at T+102 seconds.  T90 (15-350 keV) is (59.2 +- 0.3) \nseconds (estimated error including systematics).  \n\nThe photon index of the time-averaged spectrum is 1.4 +- 0.2.  \nThe fluence in the 15-350 keV band is (1.2 +- 0.2) x 10^-6 erg/cm2.  \nThe 1-s peak photon flux measured from T0+53.1 seconds in the 15-350 \nband is (0.7 +- 0.1 ) ph/cm2/s.  All the quoted errors are at the 90% \nconfidence level.",
