TITLE: GCN GRB OBSERVATION REPORT NUMBER: 4463 SUBJECT: GRB 060110: Swift-BAT detection of a burst DATE: 06/01/10 08:42:15 GMT FROM: Scott Barthelmy at NASA/GSFC S. Zane (UCL-MSSL), S. Barthelmy (GSFC), A. J. Blustin (UCL-MSSL), N. Gehrels (GSFC), C. Markwardt (GSFC/UMD), J. Norris (GSFC), K. Page (U Leicester), D. Palmer (LANL) on behalf of the Swift team: At 08:01:17 UT, Swift-BAT triggered and located GRB 060110 (trigger=176702). The spacecraft did not slew because of the Moon observing constraint. The BAT on-board calculated location is RA,Dec 72.741d,+28.380d {04h 50m 58s,+28d 22' 48"} (J2000), with an uncertainty of 3 arcmin (radius, 90% containment, stat+sys). The BAT light curve shows a single FRED-like peak structure with a total duration of 15 sec. The peak count rate was ~5000 counts/sec (15-350 keV), at ~2 seconds after the trigger. We are currently in the Malindi downlink gap, so it will be at least 5 hours before we get the full data set on this burst. This burst will remain in the Moon observing constriant for 2.8 days.
