Ukwatta (GWU) (i.e. the Swift-BAT team):\n\nUsing the data set from T-300 to T+1197 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 081230 (trigger #338633)\n(La Parola, et al., GCN Circ. 8753).  The BAT ground-calculated position is\nRA, Dec = 37.330, -25.145 deg which is \n   RA(J2000)  =  02h 29m 19.2s \n   Dec(J2000) = -25d 08' 42.6\" \nwith an uncertainty of 1.4 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 100%.\n \nThe mask-weighted light curve consists of a series of overlapping peaks ranging\nfrom T+5 sec to T+70 sec, with the strongest emission at ~T+50 seconds.\nT90 (15-350 keV) is 60.7 +- 13.8 sec (estimated error including systematics).\n \nThe time-averaged spectrum from T-14.4 to T+62.4 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.97 +- 0.16.  The fluence in the 15-150 keV band is 8.2 +- 0.8 x 10^-7 erg/cm2.\nThe 1-sec peak photon flux measured from T+46.63 sec in the 15-150 keV band\nis 0.7 +- 0.1 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/338633/BA/",
