Sakamoto (AGU), M. Stamatikos (OSU),\nT. N. Ukwatta (LANL) (i.e. the Swift-BAT team):\n\nUsing the data set from T-239 to T+963 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 190512A (trigger #903357)\n(Bernardini, et al., GCN Circ. 24501).  The BAT ground-calculated position is\nRA, Dec = 82.402, -7.582 deg which is \n  RA(J2000)  =  05h 29m 36.5s \n  Dec(J2000) = -07d 34' 56.1\" \nwith an uncertainty of 2.9 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 83%.\n\nThe mask-weighted light curve shows a single FRED-shaped profile, starting at\nT-12 sec, peaking close to T+0 sec, and slowly decaying to background by \nT+50 sec.  T90 (15-350 keV) is 40.1 +- 11.3 sec (estimated error including systematics).\n\nThe time-averaged spectrum from T-9.70 to T+43.31 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n2.07 +- 0.14.  The fluence in the 15-150 keV band is 1.3 +- 0.1 x 10^-6 erg/cm2.\nThe 1-sec peak photon flux measured from T-2.78 sec in the 15-150 keV band\nis 1.0 +- 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/903357/BA/",
