Patel (NASA/MSFC) report on \nbehalf of a larger collaboration:\n\nWe executed a Chandra ToO observation of GRB 051221A beginning at 2005-12-22\n13:55:20 UT  (130 ks after the burst) and lasting for 30.2 ks.  A fading \nX-ray source was found within the XRT error circle (Burrows et al., GCN \n4366) at\n\n   RA(J2000)  =  21:54:48.626\n   Dec(J2000) = +16:53:27.16\n\nChandra positions have typical uncertainties of 0.5 arcseconds \n(radius).  This\nposition is 0.55 arcseconds from the optical counterpart identified by \nBloom et al. (GCN 4368)\nand 0.34 arcseconds from the position reported by Berger (GCN 4369)",
