We began observations at 17:15UT\n(~5h30m after GRB time).\nOptical source (about 13.6 in R) was detected at the position given\nin Circ 1985 in the beginning of observations. At 20:20UT (~8h40m after\nGRB\ntime) magnitude became more than one magnitude fainter and it was about\n14.8 in R. The OT seems to become fainter very slowly.\nAt present we have about 100 images of the OT. These images are\nbeing processed.\n\nThese are preliminary results.",
