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 190320A (trigger #893808)\n(Gropp, et al., GCN Circ.23973).  The BAT ground-calculated position is\nRA, Dec = 117.824, -45.876 deg which is \n  RA(J2000)  =  07h 51m 17.8s \n  Dec(J2000) = -45d 52' 33.3\" \nwith an uncertainty of 1.9 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 29%.\n\nThe mask-weighted light curve shows a single episode with some superimposed\nstructure from roughly T-25 to T+40 sec.  The spacecraft slewed away from the \nburst position at around T+500 sec. T90 (15-350 keV) is 64.0 +- 12.1 sec \n(estimated error including systematics).\n\nThe time-averaged spectrum from T-27.20 to T+44.80 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.20 +- 0.20.  The fluence in the 15-150 keV band is 2.7 +- 0.3 x 10^-6 erg/cm2.\nThe 1-sec peak photon flux measured from T-0.20 sec in the 15-150 keV band\nis 1.3 +- 0.5 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/893808/BA/",
