At 15:22:35 UT, Swift-BAT triggered and located GRB 051113 (trigger=163765). The spacecraft did not slew to this burst because of the Sun-angle observing constraint; this burst is 39 deg from the Sun. The BAT on-board calculated location is RA,Dec 187.222d,-26.391d {12h 28m 53s,-26d 23′ 25″} (J2000), with an uncertainty of 3 arcmin (radius, 90% containment, stat+sys).

The BAT light curve shows a single peak with a total duration of ~10 sec. The peak count rate was ~1400 counts/sec (15-350 keV), at ~2 seconds after the trigger.
