We observed field of the Swift GRB 110801A (Pasquale et al. GCN 12228)
with Zeiss-600 telescope of Mt.Terskol observatory in R filter starting on
Aug. 02 (UT) 00:25. In a stacked image we clearly detect optical afterglow
(Pasquale et al. GCN 12228, Zheng et al. GCN 12229). A photometry is based
on the USNO B1.0 star 1709-0023450 (05 57 24.91 +80 57 39.8) assuming
R=15.73.
