Ukwatta (MSU)\n(i.e. the Swift-BAT team):\n \nUsing the data set from T-60 to T+243 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 110610A (trigger #455155)\n(Marshall, et al., GCN Circ. 12065).  The BAT ground-calculated position is\nRA, Dec = 308.205, 74.827 deg, which is \n   RA(J2000)  =  20h 32m 49.1s \n   Dec(J2000) = +74d 49' 37.3\" \nwith an uncertainty of 1.0 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 71%.\n \nThe mask-weighted light curve shows several overlapping peaks starting\nat ~T-15 sec, with the first peak at ~T+3 sec, the highest peak at ~T+35 sec,\nand ending at ~T+55 sec.  Emission may continue (~1-sigma level) out to T+170 sec.\nT90 (15-350 keV) is 46.4 +- 5.7 sec (estimated error including systematics).\n \nThe time-averaged spectrum from T-11.1 to T+58.0 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.51 +- 0.05.  The fluence in the 15-150 keV band is 4.9 +- 0.1 x 10^-6 erg/cm2.\nThe 1-sec peak photon flux measured from T+34.42 sec in the 15-150 keV band\nis 4.2 +- 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/455155/BA/",
