Bikmaev, N. Sakhibullin (KSU/AST),\n\nreport:\n\nWe observed the field around the position of the optical counterpart\n(Rykoff et al. GCN5220, Page et al., GCN5221) of GRB060605 (Swift trigger\n213630) with the Russian-Turkish 1.5-m telescope (RTT150, Bakirlitepe,\nTUBITAK National Observatory, Turkey), at the beginning of June 07, about \n31.1 hours after the burst. A series of frames was taken in R band with \nTFOSC. The afterglow is detected on combined image.\n\nhttp://www.tug.tubitak.gov.tr/~irekk/grb/grb060605/GRB060605_0607_RTT150.JPG\n\nUsing USNO-B1 star (RA=21:28:40.26, DEC=-06:03:44.5, R2MAG=15.37)\nwe estimate the following R magnitude for the OT:\n\n     t-t0  m_R     err\n     31.1  23.0    0.2\n\nUsing all data (Khamitov et al., GCN5224) we estimate the power-law decay\nindex in R as -1.7+-0.02, which did not changed since ~5.6 hours after the \nburst.\n\nOur R lightcurve can be found at:\n\nhttp://www.tug.tubitak.gov.tr/~irekk/grb/grb060605/GRB060605_lc0607.jpg\n\nThis message may be cited.",
