GCN Circular 8148
P.A. Evans and J.P. Osborne (U. Leicester) report on behalf of the Swift-XRT team: Using 9.1 ks of XRT Photon Counting mode data and 35 UVOT images, we find an astrometrically corrected X-ray position for SGR 0501+4516 (using the XRT-UVOT alignment and matching UVOT field sources to the USNO-B1 catalogue): RA, Dec = 75.27834, +45.27649 which is equivalent to: RA (J2000): 05h 01m 6.80s Dec (J2000): +45d 16' 35.4" with an uncertainty of 1.4 arcsec (radius, 90% confidence). This position is consistent with the possible infra-red counterpart (Tanvir & Varricatt, GCN Circ. 8126). The position enhancement process is described by Goad et al. (2007, A&A, 476, 1401 http://www.swift.ac.uk/xrt_positions/Goad.pdf), the current algorithm is an extension of this method. This circular is an official product of the Swift-XRT team.
