TITLE: GCN CIRCULAR NUMBER: 6859 SUBJECT: GRB 071010: Swift detection of a burst DATE: 07/10/10 03:56:03 GMT FROM: David Palmer at LANL A. Moretti (INAF-OAB), W. H. Baumgartner (GSFC/UMBC), N. Gehrels (NASA/GSFC), S. T. Holland (CRESST/USRA/GSFC), D. M. Palmer (LANL), M. Stamatikos (NASA/ORAU) and T. N. Ukwatta (GSFC/GWU) report on behalf of the Swift Team: At 03:41:12 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 071010 (trigger=293707). The BAT on-board calculated location is RA, Dec 288.101, -32.379 which is RA(J2000) = 19h 12m 24s Dec(J2000) = -32d 22' 42" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a broad structure with a duration of about 30 sec. The peak count rate was ~600 counts/sec (15-350 keV), at ~2 sec after the trigger. Because Swift is in the process of returning to normal operations, automatic slewing to GRBs is currently disabled outside of business hours (US EDT). Therefore, there are no prompt XRT or UVOT observations of this burst. Burst Advocate for this burst is A. Moretti (moretti AT merate.mi.astro.it). Please contact the BA by email if you require additional information regarding Swift followup of this burst. In extremely urgent cases, after trying the Burst Advocate, you can contact the Swift PI by phone (see Swift TOO web site for information: http://www.swift.psu.edu/too.html.)
