TITLE: GCN CIRCULAR NUMBER: 14391 SUBJECT: GRB 130419A: Swift detection of a burst DATE: 13/04/19 13:39:56 GMT FROM: David Palmer at LANL N. P. M. Kuin (UCL-MSSL), D. N. Burrows (PSU), V. D'Elia (ASDC), P. A. Evans (U Leicester), S. T. Holland (STScI), J. A. Kennea (PSU), F. E. Marshall (NASA/GSFC), K. L. Page (U Leicester), D. M. Palmer (LANL), P. Romano (INAF-IASFPA), M. H. Siegel (PSU) and R. L. C. Starling (U Leicester) report on behalf of the Swift Team: At 13:30:29 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 130419A (trigger=553918). Swift did not slew due to Sun constraint. The BAT on-board calculated location is RA, Dec 355.271, +9.977 which is RA(J2000) = 23h 41m 05s Dec(J2000) = +09d 58' 38" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). As is usual for image triggers, there is no obvious variation in BAT's immediately-avaialble lightcurve. Due to a Sun observing constraint, Swift cannot slew to the BAT position until 00:33 UT on 2013 May 06. There will thus be no XRT or UVOT data for this trigger before this time. Burst Advocate for this burst is N. P. M. Kuin (n.kuin AT 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.)
