Leicester) report on behalf of the \nSwift-XRT team:\n\nUsing 3971 s of XRT Photon Counting mode data and 2 UVOT images for the \nINTEGRAL burst GRB 100103A, we find an astrometrically corrected X-ray \nposition (using the XRT-UVOT alignment and matching UVOT field sources to \nthe USNO-B1 catalogue): RA, Dec = 112.37270, -34.49020 which is equivalent \nto:\n\nRA (J2000):  07 29 29.46\nDec (J2000): -34 29 24.9\n\nwith an uncertainty of 1.7 arcsec (radius, 90% confidence).\n\nThis position may be improved as more data are received.  The latest \nposition can be viewed at http://www.swift.ac.uk/xrt_positions. Position \nenhancement is described by Goad et al. (2007, A&A, 476, 1401) and Evans \net al. (2009, MNRAS, 397, 1177).\n\nThis circular is an official product of the Swift-XRT team.",
