TITLE: GCN CIRCULAR NUMBER: 12199 SUBJECT: GRB 110726A: Swift/UVOT Detection DATE: 11/07/26 04:02:40 GMT FROM: Mike Siegel at PSU/Swift MOC M.H. Siegel (PSU) and C. A. Wolf (PSU) report on behalf of the Swift/UVOT team: Swift/UVOT began observations of the field of GRB 110726A (Wolf et al. 2011, GCN 12196) 59 seconds after the BAT trigger. The 150 second finding chart in the White filter reveals a candidate afterglow in the rapidly available 2.7'x2.7' sub-image at: RA(J2000) = 19:06:52.06 = 286.71693 DEC(J2000) = +56:04:16.6 = 56.0713 with a 90%-confidence error radius of about 0.6 arc sec. This is consistent with the afterglow reported by both the XRT (Wolf et al.) and ROTSE (Schaefer et al., 2011, GCN 12197). The estimated magnitude is 17.80 with a 1-sigma error of about 0.06. No correction has been made for the expected extinction corresponding to E(B-V) of 0.08.
