The BAT ground-calculated position is\nRA, Dec = 356.783, 0.310 deg which is \n   RA(J2000)  =  23h 47m 08.0s \n   Dec(J2000) = +00d 18' 35.1\" \nwith an uncertainty of 1.2 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 68%.\n \nThe mask-weighted light curve shows a cluster of overlapping peaks starting\nat ~T-20, the tallest at T+25 sec, and ending at ~T+120 sec.\nT90 (15-350 keV) is 106 +- 5 sec (estimated error including systematics).\n \nThe time-averaged spectrum from T-21.2 to T+111.4 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.34 +- 0.06.  The fluence in the 15-150 keV band is 4.6 +- 0.2 x 10^-6 erg/cm2.\nThe 1-sec peak photon flux measured from T+24.68 sec in the 15-150 keV band\nis 2.0 +- 0.2 ph/cm2/sec.  All the quoted errors are at the 90% confidence\nlevel. \n \nThe results of the batgrbproduct analysis are available at\nhttp://gcn.gsfc.nasa.gov/notices_s/319584/BA/",
