GCN Circular 5723
E. Troja (U.Leicester,INAF/IASFPa), K. L. Page (U.Leicester), N. Gehrels (NASA/GSFC) and D. N. Burrows (PSU) report on behalf of the Swift XRT team: Using the first 22 ks of XRT PC observations we detected 6 serendipitous X-ray sources with S/N>3 in the field of view of GRB 061006. Comparing the X-ray centroids to positions of nearby infrared sources, listed in the 2MASS catalogue, we noted that a systematic offset is present. We then improved the XRT position considering three infrared/X-ray associations and we obtained the new X-ray afterglow position: RA(J2000)= 07h 24m 07.33s Dec(J2000)= -79d 11' 55.77'' with a shift of Delta RA=2.73 arcsec and Delta Dec=-1.03 arcsec with respect to the previous one, reported in GCN Circ. 5703. The corresponding error radius is 2.2 arcsec (90% containment). This new position lies 1.1 arcsec from the optical afterglow candidate proposed by Malesani et al. (GCN Circ. 5718). This circular is an official product of the Swift-XRT team.
