M. Andreev, A. Sergeev (Terskol Branch of Institute of Astronomy), A. 
Pozanenko (IKI) on behalf of larger GRB follow up collaboration report:

We observed field of the Swift  GRB 110205A (Beardmore et al, GCN 11629) 
with Zeiss-600 telescope of Mt.Terskol observatory in R,V filters starting 
on Feb. 05 (UT) 02:16.  We clearly detect optical afterglow  (Beardmore et 
al, GCN 11629, Klotz et al, GCN 11630, Schaefer  et al, GCN 11631, Mundell 
et al, GCN 11633) and confirm the optical flare at ~ 1140 s  (Schaefer et 
al, GCN 11631, Klotz et al, GCN 11632, Chester et al, GCN 11634) with 
maximal brightness R ~ 13.7.
