TITLE: GCN CIRCULAR NUMBER: 14204 SUBJECT: GRB 130215A: Swift detection of a burst DATE: 13/02/15 01:50:26 GMT FROM: Scott Barthelmy at NASA/GSFC V. D'Elia (ASDC), S. D. Barthelmy (GSFC), N. Gehrels (NASA/GSFC), J. A. Kennea (PSU), A. Y. Lien (NASA/GSFC/ORAU), C. B. Markwardt (NASA/GSFC) and B. Sbarufatti (INAF-OAB/PSU) report on behalf of the Swift Team: At 01:31:30 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 130215A (trigger=548760). Swift did not slew because of Moon constraint. The BAT on-board calculated location is RA, Dec 43.479, +13.371 which is RA(J2000) = 02h 53m 55s Dec(J2000) = +13d 22' 14" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows a single peak with a duration of about 40 sec. The peak count rate was ~1300 counts/sec (15-350 keV), at ~1 sec after the trigger. Due to a Moon observing constraint, Swift cannot slew to the BAT position until 14:00 UT on 2013 February 18. There will thus be no XRT or UVOT data for this trigger before this time. 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.)
