V.Rumyantsev (CrAO), V.Biryukov (SAI, MSU), and A.Pozanenko (IKI) on behalf
of larger GRB follow up collaboration report:

We have observed the GRB051008 error box (Marshall et al., GCN4069) with 2.6
m Shajn telescope of CrAO. The observation start on Oct. 8, 17:05:08 (UT),
i.e 38 minutes after the burst onset.  We found an optical source  within
XRT  error circle (Perri et al., GCN4073) which is not present in DSS2 (R):

RA(J2000) =13 31 29.98
Dec       =+42 05 52.06

Preliminary photometry against of USNO A2.0 is  R=21.4+-0.1.

Finding chart of the optical source can be found at

More detailed analysis and observations are in progress.
No optical source is detected in the place of radio source (Cameron et al.,
