TITLE: GCN CIRCULAR NUMBER: 19578 SUBJECT: GRB 160625A: Swift-XRT observations DATE: 16/06/25 23:51:03 GMT FROM: Phil Evans at U of Leicester D.N. Burrows (PSU), J.A. Kennea (PSU), S. Campana (INAF-OAB), G. Cusumano (INAF-IASF PA), P.A. Evans (U. Leicester) and J.P. Osborne (U. Leicester) report on behalf of the Swift-XRT team: The XRT began observing the field of GRB 160625A at 23:02:36.8 UT, 1325.3 seconds after the BAT trigger. Using promptly downlinked data we find an uncatalogued X-ray source located at RA, Dec 176.91418, -65.14362 which is equivalent to: RA(J2000) = 11h 47m 39.40s Dec(J2000) = -65d 08' 37.0" with an uncertainty of 5.8 arcseconds (radius, 90% containment). This location is 112 arcseconds from the BAT onboard position, within the BAT error circle. This position may be improved as more data are received; the latest position is available at http://www.swift.ac.uk/sper. We cannot determine whether the source is fading at the present time. No spectrum from the promptly downlinked event data is yet available to determine the column density.
