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.
