TITLE: GCN CIRCULAR NUMBER: 34393 SUBJECT: GRB 230812B: Preliminary Swift/XRT localization DATE: 23/08/13 04:03:06 GMT FROM: Jamie Kennea at Penn State U J. A. Kennea (PSU) on behalf ot the Swift team, In a target-of-opportunity observation taken starting 02:00UT on August 13th, 2023, pointed at the LAT position (GCN 34392) of GRB 230812B (GCN 34391), we find a previously uncatalogued X-ray point source in preliminary data from Swift’s X-ray Telescope. The preliminary position is RA/Dec (J2000) = 249.13957, 47.854760, which is equivalent: RA(J2000) = 16h 36m, 33.4s, Dec(J2000) = +47d 51m 17.1s, with an estimate error of 10 arcseconds radius. Please note this position is based upon preliminary data, reported rapidly to aide follow-up. An updated position will be reported via GCN ASAP.
