Ukwatta (MSU)\n(i.e. the Swift-BAT team):\n  \nUsing the data set from T-70 to T+963 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 130929A (trigger #572308)\n(Marshall, et al., GCN Circ. 15269).  The BAT ground-calculated position is\nRA, Dec = 135.028, -47.554 deg which is\n    RA(J2000)  =  09h 00m 06.7s\n    Dec(J2000) = -47d 33' 14.6\"\nwith an uncertainty of 1.6 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 44%.\n  \nThe mask-weighted light curve shows a single FRED peak.  T90 (15-350 keV) is\n11.10 +- 2.98 sec (estimated error including systematics).\n  \nThe time-averaged spectrum from T-1.93 to T+11.50 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n2.00 +- 0.18.  The fluence in the 15-150 keV band is 6.9 +- 0.8 x 10^-07 erg/cm2.\nThe 1-sec peak photon flux measured from T+1.32 sec in the 15-150 keV band\nis 1.7 +- 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/572308/BA/",
