Gogus (Sabanci Uni.)\n\nreport:\n\nThe optical afterglow of GRB 091015 (Ferrigno et al., GCN 10025, Gotz et\nal., GCN 10026) was observed with Russian-Turkish 1.5-m telescope (RTT150,\nBakirlitepe, TUBITAK National Observatory, Turkey) in partially cloudy\nconditions. We obtained a serie of 60s images in R centered at October 16,\n17:40 UT, i.e. 0.76 days after the burst. The limiting magnitude in combined\nimage is estimated as R=~22. We do not detect any new optical object as\ncompared to DSS II red plate.",
