Gogus (Sabanci Uni.)\n\nreport:\n\nThe field of GRB 120302A (Sakamoto et al., GCN 13000) was observed\nwith Russian-Turkish 1.5-m telescope (RTT150, Bakirlitepe, TUBITAK\nNational Observatory, Turkey) on March 02, 2012, during UT\n19:20--20:05, approximately 18 hours after the burst. A serie of 7\nexposures by 300 sec each in Rc filter was obtained at moderate\nweather conditions and seeing of 1.7 arcsec.\n\nWe clearly detected optical source at the position of XRT, UVOT and\nGROND OT candidate (Elliott et al., GCN 13003, Sakamoto et al., GCN\n13012). In our combined image we estimated brightness of OT as Rc =\n21.14+/-0.08, calibrated against USBO-B1.0 star (R2=17.31 mag) at\nR.A. (2000.0) = 08:09:36.74, Dec. (2000.0) = +29:37:54.9\n\nWe also made a serie of 300 sec exposures on March 08, 2012, UT (mean)\n= 21:05. OT is not seen at the limit of combined image of R ~ 22.4",
