TITLE: GCN CIRCULAR NUMBER: 4533 SUBJECT: GRB 060117: Swift-BAT detection of a bright burst DATE: 06/01/17 07:22:11 GMT FROM: Scott Barthelmy at NASA/GSFC S. Campana (INAF-OAB), S. Barthelmy (GSFC), N. Gehrels (GSFC), C. Gronwall (PSU), H. Krimm (GSFC/USRA), C. Markwardt (GSFC/UMD), K. Page (U Leicester), D. Palmer (LANL), M. Perri (ASDC) on behalf of the Swift team: At 06:50:01 UT, Swift-BAT triggered and located GRB 060117 (trigger=177666). The spacecraft did not slew because of the Sun observing constraint. It will come out of the Swift observing constraint on 07 Feb 2006. The BAT on-board calculated location is RA,Dec 327.926d,-59.980d {21h 51m 42s,-59d 58' 49"} (J2000), with an uncertainty of 3 arcmin (radius, 90% containment, stat+sys). The BAT light curve shows a bright multi-peak structure with a total duration of ~25 sec. The peak count rate was ~40,000 counts/sec (15-350 keV), at ~12 seconds after the trigger. We note that this is within 3 arcmin of the bright (J=13.0 mag) galaxy IRAS 21482-6015.
