Leicester), A.P. Beardmore (U. Leicester) and report on behalf of the Swift-XRT team: report on behalf of the Swift-XRT team: We have analysed 9.6 ks of XRT data for the Fermi/LAT-detected burst GRB 140104B, from 55.4 ks to 833.9 ks after the Fermi/LAT trigger. The data are entirely in Photon Counting (PC) mode. The refined XRT position is RA, Dec = 218.7543, -9.0282 which is equivalent to: RA (J2000): 14 35 01.03 Dec(J2000): -09 01 41.5 with an uncertainty of 4.0 arcsec (radius, 90% confidence). This position is 8.4 arcmin from the Fermi/LAT position. We cannot determine at the present time whether the source is fading. The results of the XRT-team automatic analysis are available at http://www.swift.ac.uk/xrt_products/00020337. This circular is an official product of the Swift-XRT team.
