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

We observed the error box of Swift GRB 081210 (Krimm  et al, GCN  8648) in R 
band on Dec. 10 between (UT)  22:31:15 -  23:05:19 with Shajn telescope of 
CrAO. Inside the enhanced XRT error box (Osborne et al. GCN 8650) we do not 
detect optical afterglow (Krimm   et al, GCN 8648). A photometry based on 
0787-0047183 USNO B1.0 star  (04:41:55.26 -11:14:39.0) assuming  R2=16.33 is 
following:

T0+    Filter,  Exp.,     UL
(h)             (s)       (3 sigma)
