TITLE: GCN CIRCULAR NUMBER: 8014 SUBJECT: GRB 080725: Swift detection of a burst DATE: 08/07/25 10:43:53 GMT FROM: David Palmer at LANL H. A. Krimm (CRESST/GSFC/USRA), W. H. Baumgartner (GSFC/UMBC), A. P. Beardmore (U Leicester), P. A. Evans (U Leicester), S. D. Hunsberger (PSU), S. Immler (CRESST/GSFC/UMD), J. Mao (INAF-OAB), P. T. O'Brien (U Leicester), K. L. Page (U Leicester), D. M. Palmer (LANL), D. Perez (U Leicester), B. Preger (ASDC), R. L. C. Starling (U Leicester), G. Stratta (ASDC) and L. Vetere (PSU) report on behalf of the Swift Team: At 10:26:14 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 080725 (trigger=317888). The BAT on-board calculated location is RA, Dec 121.715, -13.990 which is RA(J2000) = 08h 06m 52s Dec(J2000) = -13d 59' 23" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a double-peaked structure with a duration of about 60 sec. The peak count rate was ~2800 counts/sec (15-350 keV), at ~3 sec after the trigger. Due to proximity to the Sun, Swift cannot slew to the BAT position. The source will not be observable until September. There will thus be no XRT or UVOT data for this trigger. Burst Advocate for this burst is H. A. Krimm (krimm AT milkyway.gsfc.nasa.gov). 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.)
