Evans (U. Leicester) reports on behalf of the Swift-XRT team:

Swift-XRT has conducted further observations of the field of the
Fermi/GBM-detected burst GRB 231129C. The observations now extend from
T0+34.8 ks to T0+172.6 ks. The source previously reported, "Source 2",
is believed to be the afterglow.  The position of this source is RA,
Dec=11.1769, -81.9936 which is equivalent to:

RA (J2000): 00:44:42.45
Dec(J2000): -81:59:37.0

with an uncertainty of 9.5 arcsec (radius, 90% confidence).  This
position is 22.4 arcmin from the Fermi/GBM position.  We cannot
determine at the present time whether the source is fading.

The results of the XRT-team automatic analysis are available at

The results of the full analysis of the tiled XRT observations are
