Sakamoto (GSFC/UMBC),\nG. Sato (GSFC/ISAS), M. Stamatikos (GSFC/ORAU), T. Ukwatta (GWU)\n(i.e. the Swift-BAT team):\n \nUsing the data set from T-240 to T+962 sec from recent telemetry downlinks,\nwe report further analysis of BAT GRB 080123 (trigger #301578)\n(Ukwatta, et al., GCN Circ. 7203).  The BAT ground-calculated position is\nRA, Dec = 338.974, -64.930 deg which is \n   RA(J2000)  =  22h 35m 53.8s \n   Dec(J2000) = -64d 55' 48\" \nwith an uncertainty of 4.1 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 20%.\n \nThe mask-weighted light curve shows two well-separated peaks.  The first\nstarts at ~T+0.3 sec and is no wider than 64 msec.  The second peak\nstarts at ~T+0.6 sec with a FRED-like shape and a duration of ~256 msec.\nThere is soft extended emission lasting ~120 sec.  T90 (15-350 keV) is\n115 +- 30 sec (estimated error including systematics).\n \nThe time-averaged spectrum from T+0.3 to T+122.2 sec (SHB plus extended\nemmission) is best fit by a simple power-law model.  The power law index\nof the time-averaged spectrum is 2.15 +- 0.54.  The fluence in the\n15-150 keV band is 5.7 +- 1.7 x 10^-7 erg/cm2.  The 1-sec peak photon flux\nmeasured from T-0.05 sec in the 15-150 keV band is 1.8 +- 0.4 ph/cm2/sec.\nAll the quoted errors are at the 90% confidence level. \n \nThe results of the batgrbproduct analysis are available at\nhttp://gcn.gsfc.nasa.gov/notices_s/301578/BA/",
