Observers notes: (these notes are added by observers at the end of followup)
The observations started (after the dusk) 12h 19m after the GRB trigger, with our Schmidt telescope D=400 mm F/D=3 Weather conditions were very good. We co-added 2 series of 10 unfiltered CCD exposures of 120s each. We did not found any optical counterpart in the Swift-XRT error circle (Evans & Marshall, GCN Circular 14635) at our following limiting magnitude: Start End Mlim T0+ T0+ 12.3h 13.0h 19.0
