behalf of the Swift XRT team, report:

We have posted online the results of the analysis of the X-ray afterglow 
of GRB 041223 (Tueller et al., GCN 2898; Burrows et al., GCN 2901). 
Plots displaying the lightcurve and the spectrum can be seen at

http://www.merate.mi.astro.it/~taglia/GRB041223

At the same page, a finding chart for the afterglow is also shown, 
reporting a refined X-ray position obtained after running the XRT 
pipeline processing software. The coordinates are

R.A. =  06:40:47.4
Dec. = -37:04:22.3

This position is just 1.5" far from the optical/NIR afterglow (Berger et 
al., GCN 2902; Malesani et al., GCN 2903).
