Ukwatta (MSU)\n(i.e. the Swift-BAT team):\n  \nUsing the data set from T-120 to T+182 sec from the recent telemetry downlink,\nwe report further analysis of the burst from SGR 1745-29 (trigger #565443)\n(Barthelmy, et al., GCN Circ. 15069).  The BAT ground-calculated position is\nRA, Dec = 266.403, -29.017 deg which is\n    RA(J2000)  =  17h 45m 36.8s\n    Dec(J2000) = -29d 01' 02.3\"\nwith an uncertainty of 1.9 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 100%.\n  \nThe mask-weighted light curve shows a single peak with some substructure at\nlow significance.  T90 (15-350 keV) is 0.011 +- 0.002 sec (estimated error\nincluding systematics).\n  \nThe time-averaged spectrum from T+0.00 to T+0.01 sec is best fit by functions\nexponentially declining with energy in the BAT energy range.  A blackbody fit\nis formally the best fit with kT = 8.9 +/- 0.2.  A simple powerlaw fit has a\npower law index of the time-averaged spectrum of 2.54 +- 0.26.  The fluence in\nthe 15-150 keV band is 9.2 +- 1.6 x 10^-09 erg/cm2. The 1-sec peak photon flux\nmeasured from T+0.00 sec in the 15-150 keV band is 22.1 +- 3.6 ph/cm2/sec.  All\nthe quoted errors are at the 90% confidence level.\n  \nThe results of the batgrbproduct analysis are available at\nhttp://gcn.gsfc.nasa.gov/notices_s/565443/BA/",
