GCN Circular 16470
P. D'Avanzo, M.G. Bernardini, A. Melandri (INAF/OAB), P.A. Evans and M.R. Goad (U. Leicester) report on behalf of the Swift-XRT team: Using promptly downlinked data we find an uncatalogued and fading X-ray source. Using 40 s of XRT Photon Counting mode data and 1 UVOT image, we find an astrometrically corrected X-ray position (using the XRT-UVOT alignment and matching UVOT field sources to the USNO-B1 catalogue): RA, Dec =40.66674, -0.38488 which is equivalent to: RA (J2000): 02 42 40.02 Dec (J2000): -00 23 05.6 with an uncertainty of 2.5 arcsec (radius, 90% confidence). This position may be improved as more data are received. The latest position can be viewed at http://www.swift.ac.uk/xrt_positions. Position enhancement is described by Goad et al. (2007, A&A, 476, 1401) and Evans et al. (2009, MNRAS, 397, 1177). This circular is an official product of the Swift-XRT team.
