Rumyantsev (CrAO)\non behalf of larger GRB follow up collaboration report:\n\nWe observed   the error box of  GRB060211b (Mateos et al., GCN 4739) with\n1.5m telescope of Maidanak Astronomical Observatory. We started the\nobservation  on Jan. 11 (UT) 16:15:54 (i.e. 20.7 minutes after GRB) and took\na series of 300 sec frames in R-band. In a first frame of 300 s exposure we\ndo net reveal any optical source within refined XRT error circle (Kennea et\nal., GCN 4743). The limiting magnitude of the first  frame is 19.3R as\ncalibrated against USNO B1.0. Further analysis is underway.\n\nThis message may be cited",
