TITLE: GCN CIRCULAR NUMBER: 42726 SUBJECT: GRB 251116C: Swift/BAT arcminute localization of a burst DATE: 25/11/17 19:29:14 GMT FROM: Jimmy DeLaunay at Penn State <delauj2@gmail.com> James DeLaunay (PSU), Samuele Ronchini (GSSI), Aaron Tohuvavohu (Cosmic Frontier), Jamie A. Kennea (PSU), Tyler Parsotan (NASA GSFC) report: Swift/BAT did not localize GRB 251116C onboard (T0: 2025-11-16T15:57:41 UTC, SVOM/ECLAIRS GCN 42703). In a ground search of BAT survey data, the GRB was detected at a S/N of 7.2 in a single 300 s image (14 - 80 keV) starting at ~T0 - 192 s. The BAT position is RA, Dec = 335.3327, -10.3401 deg which is RA(J2000) = 22h 21m 19.9s Dec(J2000) = -10d 20′ 24.4″ with an estimated uncertainty of 3 arcmin radius. Source X1 detected by Swift/XRT (GCN 42721) falls inside this error circle.
