TITLE: GCN CIRCULAR NUMBER: 32445 SUBJECT: GRB 220806A: Swift detection of a burst DATE: 22/08/06 18:17:18 GMT FROM: David Palmer at LANL palmer@lanl.gov
K. L. Page (U Leicester), J.D. Gropp (PSU), S. Laha (GSFC/UMBC), D. M. Palmer (LANL), T. M. Parsotan (GSFC/UMBC/CRESSTII) and A. Tohuvavohu (U Toronto) report on behalf of the Neil Gehrels Swift Observatory Team:
At 18:08:39 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 220806A (trigger=1119268). Swift could not slew to the burst location due to a Moon constraint. The BAT on-board calculated location is RA, Dec 260.873, -26.023 which is RA(J2000) = 17h 23m 30s Dec(J2000) = -26d 01' 22" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a single peak structure with a duration of about 5 sec. The peak count rate was ~1700 counts/sec (15-350 keV), at ~0 sec after the trigger.
Due to a Moon observing constraint, Swift cannot slew to the BAT position until 18:30 UT on 2022 August 09. There will thus be no XRT or UVOT data for this trigger before this time.
Burst Advocate for this burst is K. L. Page (kimlpage1978 AT gmail.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/)
