report:
The optical afterglow of GRB 091015 (Ferrigno et al., GCN 10025, Gotz et
al., GCN 10026) was observed with Russian-Turkish 1.5-m telescope (RTT150,
Bakirlitepe, TUBITAK National Observatory, Turkey) in partially cloudy
conditions. We obtained a serie of 60s images in R centered at October 16,
17:40 UT, i.e. 0.76 days after the burst. The limiting magnitude in combined
image is estimated as R=~22. We do not detect any new optical object as
compared to DSS II red plate.
