The error box of GRB 051028 (Hurley et al., 4172) was observed with Russian-Turkish 1.5-m telescope (RTT150, Bakyrlytepe, TUBITAK National Observatory, Turkey) in R, on Oct. 28, 16:18 UT (2.7 hours after the burst). We made 10x30s exposures of the field, which includes X-ray afterglow, found later with XRT (Page et al., GCN 4205). We confirm the presence of the optical transient found by Jelinek et al. (GCN 4175) and Sahu et al. (GCN 4278) and estimate its magnitude as R=20.8+-0.15.
