TITLE: GCN CIRCULAR NUMBER: 16083 SUBJECT: Swift Trigger 595162: a possible GRB DATE: 14/04/08 17:57:13 GMT FROM: Scott Barthelmy at NASA/GSFC V. D'Elia (ASDC), S. D. Barthelmy (GSFC), M. M. Chester (PSU), N. Gehrels (NASA/GSFC), S. T. Holland (STScI), L. Izzo (URoma/ICRA), J. A. Kennea (PSU), A. Y. Lien (NASA/GSFC/ORAU), F. E. Marshall (NASA/GSFC) and B. Sbarufatti (INAF-OAB/PSU) report on behalf of the Swift Team: At 17:21:40 UT, the Swift Burst Alert Telescope (BAT) triggered and located a possible source near the known galaxy A0732-5019 (trigger=595162). Swift did not do an immediate slew because of an observing constraint. The BAT on-board calculated location is RA, Dec 113.599, -50.408, which is RA(J2000) = 07h 34m 24s Dec(J2000) = -50d 24' 26" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). As is typical for image triggers, the real-time TDRSS light curve does not show anything significant. Due to a delayed slew, there are no immediate data from the XRT or UVOT instruments. We will report on those data when they become available. Burst Advocate for this burst is V. D'Elia (delia AT asdc.asi.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.)
