on behalf of the Swift-BAT team:
At 20:34:19 UT, the Swift Burst Alert Telescope (BAT) triggered and
located on-board GRB041226. The spacecraft did not autonomously slew
to the burst since automated slewing was not yet enabled.
The BAT ground-calculated location is RA,Dec 79.544,73.349 (J2000)
with an uncertainty of 6 arcmin (radius, 3-sigma, including a systematic
uncertainty). The lightcurve is multi-peaked with a main emission duration
of ~20 s, with 4 counts/cm^2 fluence and a peak (1 second interval)
of ~0.5 counts/cm^2/s in the 15-350 keV band.
