Stamatikos (OSU), T. N. Ukwatta (LANL)\n(i.e. the Swift-BAT team):\n\nUsing the data set from T-239 to T+963 sec from the recent telemetry\ndownlink,\nwe report further analysis of BAT GRB 190611A (trigger #907950)\n(D'Elia et al., GCN Circ. 24785).  The BAT ground-calculated position is\nRA, Dec = 324.689, -56.070 deg which is\n   RA(J2000)  =  21h 38m 45.3s\n   Dec(J2000) = -56d 04' 12.6\"\nwith an uncertainty of 3.0 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 64%.\n\nThe mask-weighted light curve shows a single-peaked structure that starts\nand peaks at ~T0, and ends at ~T+40 s. T90 (15-350 keV) is 41.8 +- 30.6 sec\n(estimated error including systematics).\n\nThe time-averaged spectrum from T-0.9 to T+63.8 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.88 +- 0.54.  The fluence in the 15-150 keV band is 4.6 +- 1.6 x 10^-7\nerg/cm2.\nThe 1-sec peak photon flux measured from T+0.54 sec in the 15-150 keV band\nis 0.9 +- 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/907950/BA/",
