TITLE: GCN CIRCULAR NUMBER: 22885 SUBJECT: GRB 180704A: Swift detection of a burst DATE: 18/07/04 05:47:20 GMT FROM: David Palmer at LANL E. Sonbas (Adiyaman Univ.), A. D'Ai (INAF-IASFPA), K. L. Page (U Leicester) and D. M. Palmer (LANL) report on behalf of the Neil Gehrels Swift Observatory Team: At 05:36:42 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 180704A (trigger=846088). Swift did not immediately slew to the burst due to an Earth limb constraint. The BAT on-board calculated location is RA, Dec 32.638, +69.948 which is RA(J2000) = 02h 10m 33s Dec(J2000) = +69d 56' 52" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a complex set of peaks with a duration of about 25 sec. The peak count rate was ~4000 counts/sec (15-350 keV), at ~0 sec after the trigger. Due to an observing constraint, Swift will not slew until T0+48.1 minutes. There will be no XRT or UVOT data until this time. Burst Advocate for this burst is E. Sonbas (edasonbas AT yahoo.com). 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.)
