Ukwatta (MSU)\n(i.e. the Swift-BAT team):\n \nUsing the data set from T-471 to T+639 sec from recent telemetry downlinks,\nwe report further analysis of BAT GRB 110808A (trigger #458918)\n(Stratta, et al., GCN Circ. 12256).  The BAT ground-calculated position is\nRA, Dec = 57.322, -44.177 deg which is \n   RA(J2000)  =  03h 49m 17.2s \n   Dec(J2000) = -44d 10' 35.4\" \nwith an uncertainty of 2.7 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 76%.\n \nThe mask-weighted light curve shows a FRED pulse shape starting at ~T+0 sec,\npeaking at ~T+1 sec, and returning the baseline at ~T+50 sec.\nT90 (15-350 keV) is 48 +- 23 sec (estimated error including systematics).\n \nThe time-averaged spectrum from T-7.4 to T+40.6 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n2.32 +- 0.43.  The fluence in the 15-150 keV band is 3.3 +- 0.8 x 10^-7 erg/cm2.\nThe 1-sec peak photon flux measured from T+0.06 sec in the 15-150 keV band\nis 0.4 +- 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/458918/BA/",
