Sakamoto (AGU),\nM. Stamatikos (OSU), T. N. Ukwatta (LANL) (i.e. the Swift-BAT team):\n\nUsing the data set from T-239 to T+240 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 191029A (trigger #932058)\n(Evans, et al., GCN Circ. 26088).  The BAT ground-calculated position is\nRA, Dec = 352.140, -40.464 deg which is \n  RA(J2000)  =  23h 28m 33.6s \n  Dec(J2000) = -40d -27' -49.8\" \nwith an uncertainty of 1.8 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 46%.\n\nThe mask-weighted light curve shows a pair of weak pulses spanning the period \nfrom approximately T-5 to T+35 seconds. T90 (15-350 keV) is 39.5 +- 7.9 sec \n(estimated error including systematics).\n\nThe time-averaged spectrum from T-1.05 to T+45.85 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.77 +- 0.21.  The fluence in the 15-150 keV band is 1.1 +- 0.1 x 10^-6 erg/cm2.\nThe 1-sec peak photon flux measured from T+1.90 sec in the 15-150 keV band\nis 1.1 +- 0.3 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/932058/BA/",
