TITLE: GCN CIRCULAR NUMBER: 15012 SUBJECT: GRB 130719A: Swift detection of a burst DATE: 13/07/19 06:07:14 GMT FROM: David Palmer at LANL F. E. Marshall (NASA/GSFC), J. R. Cummings (NASA/UMBC), V. D'Elia (ASDC), C. Gronwall (PSU), P. T. O'Brien (U Leicester) and D. M. Palmer (LANL) report on behalf of the Swift Team: At 05:47:49 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 130719A (trigger=562625). Swift could not slew to the burst due to a Sun constraint. The BAT on-board calculated location is RA, Dec 89.039, -11.585 which is RA(J2000) = 05h 56m 09s Dec(J2000) = -11d 35' 03" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve is dominated by variation from Vela X-1, which is also in the FOV, so nothing can be stated about the burst light curve for this image trigger at this time. Due to the Sun constraint, XRT and UVOT will not be able to observe the burst location until July 26. Burst Advocate for this burst is F. E. Marshall (marshall 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.)
