Using the 152 cm Loiano telescope equipped with the BFOSC
camera system, we  obtained two 10 min.  Rc-band images of
the field of  GRB060929 (Markwardt et al., GCN 5654) starting
at Sept. 29.869 and 29. 878 respectively, seeing 2.6 arcsec.
In our co-added images we do not detect any new source
inside the XRT error circle. Star 1198-0273615 in the NOMAD catalog,
whose magnitude is 20.5, is detected at the 3 sigma level.
