Tueller (GSFC), \non behalf of the Swift-BAT team:\n\nUsing the data set from T-299 to T+303.0 sec from the recent telemetry\ndownlink, we report further analysis of BAT GRB 060111 (trigger #176818)  \n(Zane, et al., GCN 4479).  The BAT ground-calculated position is \n(RA,Dec) = 276.195, 37.596 {18h 24m 47.3s, 37d 35' 44.1\"} (deg; J2000)\n+- 0.8 arcmin, (radius, sys+stat, 90% containment).  The partial coding \nwas 98%.\n\nThe light curve is a single peak, rise slightly faster than its decay.\nT90 (15-350 keV) is (13 +- 1) sec (estimated error including \nsystematics).  There is a small bump of marginal significance in the \n15-50 keV band at T+280, the time of the x-ray flare observed by the\nXRT (GCN circ. #4481, Goad et al.).\n \nThe time-averaged spectrum from T-0.7 to T+14.7 is best fit by a\ncut-off power law with an Epeak of (72 +14, -8) keV and a photon\nindex of 0.8 +- 0.3.  The fluence in the 15-150 keV band is (1.18 +-\n0.05) x 10^-06 erg/cm2.  A simple power law also gives an acceptable\nfit, with a photon index of 1.63 +/- 0.07 and a fluence of (1.25 +-\n0.05) x 10^-06 erg/cm2.  The 1-sec peak photon flux measured from\nT+4.3 sec in the 15-150 keV band is (1.72 +- 0.15) ph/cm2/sec.  All\nthe quoted errors are at the 90% confidence level.",
