TITLE: GCN CIRCULAR NUMBER: 32393 SUBJECT: GRB 220714B: Swift detection of a burst DATE: 22/07/14 14:10:18 GMT FROM: Kim Page at U.of Leicester S. Laha (GSFC/UMBC), R. Brivio (INAF-OAB), P. D'Avanzo (INAF-OAB), S. Dichiara (PSU), M. Ferro (INAF-OAB), J.D. Gropp (PSU), N. J. Klingler (GSFC/UMBC/CRESSTII), F. E. Marshall (NASA/GSFC), A. Melandri (INAF-OAB), K. L. Page (U Leicester), D. M.

Williams (PSU) report on behalf of the Neil Gehrels Swift Observatory Team: At 13:58:04 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 220714B (trigger=1116221). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 47.072, -19.334 which is RA(J2000) = 03h 08m 17s Dec(J2000) = -19d 20' 02" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a complex structure with a duration of about 40 sec. The peak count rate was ~5500 counts/sec (15-350 keV), at ~13 sec after the trigger. The XRT began observing the field at 13:59:20.9 UT, 76.4 seconds after the BAT trigger. XRT found a bright, uncatalogued X-ray source located at RA, Dec 47.0803, -19.3269 which is equivalent to: RA(J2000) = 03h 08m 19.27s Dec(J2000) = -19d 19' 36.8" with an uncertainty of 5.2 arcseconds (radius, 90% containment). This location is 38 arcseconds from the BAT onboard position, within the BAT error circle. No event data are yet available to determine the column density using X-ray spectroscopy. The initial flux in the 2.5 s image was 1.70e-09 erg cm^-2 s^-1 (0.2-10 keV). UVOT took a finding chart exposure of 56 seconds with the White filter starting 121 seconds after the BAT trigger. No credible afterglow candidate has been found in the initial data products. The 2.7'x2.7' sub-image covers none of the XRT position. Data from the list of sources generated on-board are not available at this time. No correction has been made for the expected extinction corresponding to E(B-V) of 0.032. Burst Advocate for this burst is S. Laha (sib.laha 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/)
