Sato (ISAS), on behalf of the Swift-BAT team:\n\nUsing the data set from T-61 to T+122 sec from the recent telemetry\ndownlink, we report further analysis of BAT GRB 060211\n(trigger #181156)  (Mateos, et al., GCN 4739).  The BAT\nground-calculated position is (RA,Dec) = 75.076, 14.954  deg\n{5h 0m 18.2s, 14d 57' 14.5\"} (J2000) +- 2.0 arcmin, (radius, sys+stat,\n90% containment).  The partial coding was 82%.\n\nThe mask-tagged light curve shows a multi-peak structure with possible\nextended emission.  The burst started at T-12 sec with a small peak, then a\n4-sec long peak at T+0 that decays out to ~T+10 sec and low-level\nemission out to T+20 sec.  Additionally, there is a possible 10-sec wide weak\npeak centered on T+100 sec and a possible faint precursor at T-22 sec.\nT90 (15-350 keV) is (29 +- 5) sec (estimated error including systematics).\nSince we do not have data past T+122 sec, we cannot say at this time anything\nabout the extended lightcurve.  We expect that it will take at least\na day to get that data downlinked.\n\nThe time-averaged spectrum from T-11.0 to T+21.7 is best fit by\na simple power-law model. The power law index of the time-averaged spectrum\nis 1.55 +- 0.21. The fluence in the 15-150 keV band is\n(4.7 +- 0.6) x 10^-07 erg/cm2. The 1-sec peak photon flux measured from\nT+1.84 sec in the 15-150 keV band is (0.7 +- 0.1) ph/cm2/sec.\nAll the quoted errors are at the 90% confidence level.",
