TITLE: GCN CIRCULAR NUMBER: 22887 SUBJECT: GRB 180704A: Swift-XRT observations DATE: 18/07/04 07:18:52 GMT FROM: Phil Evans at U of Leicester D.N. Burrows (PSU), J.A. Kennea (PSU), M. Perri (ASDC), G. Tagliaferri (INAF-OAB), 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 180704A at 06:26:11.9 UT, 2969.1 seconds after the BAT trigger. Using promptly downlinked data we find an uncatalogued X-ray source with an enhanced position: RA, Dec 32.6592, 69.9641 which is equivalent to: RA(J2000) = 02h 10m 38.22s Dec(J2000) = +69d 57' 50.7" with an uncertainty of 2.1 arcseconds (radius, 90% containment). This location is 63 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. A power-law fit to a spectrum formed from promptly downlinked event data gives a column density consistent with the Galactic value of 4.92 x 10^21 cm^-2 (Willingale et al. 2013).
