Burrows (PSU) report on behalf of the Swift XRT team:\n\nUsing the first 22 ks of XRT PC observations we detected 6 serendipitous X-ray \nsources with S/N>3 in the field of view of GRB 061006. \nComparing the X-ray centroids to positions of nearby infrared sources, listed \nin the 2MASS catalogue, we noted that a systematic offset is present. We then \nimproved the XRT position considering three infrared/X-ray associations and \nwe obtained the new X-ray afterglow position:\n\nRA(J2000)= 07h 24m 07.33s\nDec(J2000)= -79d 11' 55.77''\n\nwith a shift of Delta RA=2.73 arcsec and Delta Dec=-1.03 arcsec with respect \nto the previous one, reported in GCN Circ. 5703. The corresponding error \nradius is 2.2 arcsec (90% containment).\nThis new position lies 1.1 arcsec from the optical afterglow candidate \nproposed by Malesani et al. (GCN Circ. 5718).\n\nThis circular is an official product of the Swift-XRT team.",
