TITLE: GCN CIRCULAR NUMBER: 12327 SUBJECT: GRB 110905A: Swift detection of a burst DATE: 11/09/05 06:34:30 GMT FROM: Scott Barthelmy at NASA/GSFC C. Pagani (U Leicester), S. D. Barthelmy (GSFC), A. P. Beardmore (U Leicester), V. D'Elia (ASDC), P. A. Evans (U Leicester), N. Gehrels (NASA/GSFC), C. Guidorzi (U Ferrara), C. J. Mountford (U Leicester), K. L. Page (U Leicester), C. J. Saxton (UCL-MSSL) and R. L. C. Starling (U Leicester) report on behalf of the Swift Team: At 05:48:40 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 110905A (trigger=502415). Swift did not slew because of the Moon observing constraint. The BAT on-board calculated location is RA, Dec 278.954, -19.318, which is RA(J2000) = 18h 35m 49s Dec(J2000) = -19d 19' 03" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve is not available at this time. Due to an observing constraint, Swift cannot slew to the BAT position, before 12:33 UT on 2011 September 8. There will thus be no XRT or UVOT data for this trigger. Burst Advocate for this burst is C. Pagani (cp232 AT star.le.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.)
