Ukwatta (MSU)\n(i.e. the Swift-BAT team):\n \nUsing the data set from T-239 to T+963 sec from recent telemetry downlinks,\nwe report further analysis of BAT GRB 120612A (trigger #524128)\n(Pagani, et al., GCN Circ. 13357).  The BAT ground-calculated position is\nRA, Dec = 126.723, -17.598 deg which is \n   RA(J2000)  =  08h 26m 53.5s \n   Dec(J2000) = -17d 35' 52.9\" \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 peak starting at ~T+15 sec,\npeaking at roughtly T+35 sec, and ending around T+150 sec with a long\nlow-level tail out to about T+380 sec.  T90 (15-350 keV) is 90 +- 14 sec\n(estimated error including systematics).\n \nThe time-averaged spectrum from T+16.9 to T+125.4 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.36 +- 0.16.  The fluence in the 15-150 keV band is 1.3 +- 0.1 x 10^-6 erg/cm2.\nThe 1-sec peak photon flux measured from T+30.20 sec in the 15-150 keV band\nis 0.5 +- 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/524128/BA/",
