Ukwatta (LANL) (i.e. the Swift-BAT team):\n\nUsing the data set from T-61 to T+242 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 141020A (trigger #615873)\n(Cenko, et al., GCN Circ. 16928).  The BAT ground-calculated position is\nRA, Dec = 225.054, 55.328 deg which is\n    RA(J2000)  =  15h 00m 12.9s\n    Dec(J2000) = +55d 19' 42.3\"\nwith an uncertainty of 1.7 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 67%.\n\nThe mask-weighted light curve shows a broad structure with multiple peaks\nsuperimposed starting at T-8 sec and continuing until T+13 sec.  T90 (15-350\nkeV) is 15.55 +- 2.05 sec (estimated error including systematics).\n\nThe time-averaged spectrum from T-5.66 to T+11.30 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.74 +- 0.18.  The fluence in the 15-150 keV band is 4.6 +- 0.6 x 10^-7\nerg/cm2. The 1-sec peak photon flux measured from T-0.20 sec in the 15-150 keV\nband is 0.7 +- 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/615873/BA/",
