Ukwatta (MSU)\n(i.e. the Swift-BAT team):\n \nUsing the data set from T-240 to T+962 sec from recent telemetry downlinks,\nwe report further analysis of BAT GRB 140506A (trigger #598284)\n(Gompertz, et al., GCN Circ. 16214).  The BAT ground-calculated position is\nRA, Dec = 276.806, -55.556 deg, which is \n   RA(J2000)  =  18h 27m 13.5s \n   Dec(J2000) = -55d 33' 20.2\" \nwith an uncertainty of 1.6 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 11%.\n \nThe mask-weighted light curve a bright initial pulse strting at ~T-5 sec,\npeaking at ~T+0.2 sec, and returning to baseline at ~T+5 sec. Then there were\ntwo weaker peaks at ~T+60 sec and at ~T+110 sec.  T90 (15-350 keV) is\n111.1 +- 9.6 sec (estimated error including systematics).\n \nThe time-averaged spectrum from T-0.20 to T+120.18 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.68 +- 0.16.  The fluence in the 15-150 keV band is 2.8 +- 0.3 x 10^-6 erg/cm2.\nThe 1-sec peak photon flux measured from T+0.00 sec in the 15-150 keV band\nis 10.9 +- 0.9 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/598284/BA/",
