TITLE: GCN CIRCULAR NUMBER: 14181 SUBJECT: GRB 130206A: Swift detection of a burst DATE: 13/02/06 19:43:58 GMT FROM: Jamie A. Kennea at PSU/Swift-XRT M. De Pasquale (UCL-MSSL), N. Gehrels (NASA/GSFC), J. A. Kennea (PSU), H. A. Krimm (CRESST/GSFC/USRA), S. R. Oates (UCL-MSSL), D. M. Palmer (LANL), B. Sbarufatti (INAF-OAB/PSU), M. H. Siegel (PSU), M. Stamatikos (OSU/NASA/GSFC) and V. N. Yershov (UCL-MSSL) report on behalf of the Swift Team: At 19:36:28 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 130206A (trigger=547918). The BAT on-board calculated location is RA, Dec 140.375, -58.160 which is RA(J2000) = 09h 21m 30s Dec(J2000) = -58d 09' 36" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a multi-peaked structure with a total duration of about 50 sec. The peak count rate was ~2500 counts/sec (15-350 keV), at ~4 sec after the trigger. Due to an observing constraint, Swift will not slew until T0+48.5 minutes. There will be no XRT or UVOT data until this time. Burst Advocate for this burst is M. De Pasquale (mdp AT mssl.ucl.ac.uk). 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.)
