Sakhibullin (KSU/AST),\n\nreport:\n\n   We observed the field around the XRT error circle (Holland et al., \nGCN5612) of GRB060926 (Swift trigger 231231) with the Russian-Turkish \n1.5-m telescope (RTT150, Bakirlitepe, TUBITAK National Observatory, \nTurkey), at the 17:45 UT of Sep 26, about 56 minutes after the burst. \nA series of frames (3*300sec) were taken in R band with TFOSC. \n  At the position of UVOT afterglow candidate (GCN5612) we detect a  faint \nsource  which faded more than 1 mag according to early detection \n(Stefanescu et al., GCN5614).  \n Using USNO-B1 star (RA=17:35:42.06, DEC=+13:02:11.7, R2MAG=18.96) we \nestimate the following R magnitude for the source:\n\n    t-t0    m_R     err\n    (min)\t\n    66.5    20.8    0.1\t\n\nThis message may be cited.",
