Pozanenko (IKI) report on behalf of larger GRB follow-up collaboration:\n\nWe observed the field of the Swift GRB 141020A  (Cenko et al., GCN 16928) with with AZT-33IK telescope of Sayan observatory (Mondy). We obtained several images on Oct. 20 starting on (UT) 13:28:20.  At the position reported in (Kuin et al., GCN 16932) we clearly detect the afterglow of GRB 141020A  (Cenko et al., GCN 16928; Kuin et al., GCN 16932). Preliminary photometry is following:\n\ndate        UT start  t-T0        Filter  Exp.
