We acquired unfiltered CCD images of GRB 100302A XRT error box (J.R.Cummings, GCN 10458) with Ondrejov 65cm telescope + CCD. AS the CCD is equipped with IR-block filter its sensitivity in I band is very close to 0. Observation started March 3 00:40 UT (4h47m after the BAT trigger). During observation which run till 03:00 UT 45 of 3 minutes exposures were obtained. On the combined image we do not identify any new object down to R ~22 magnitude. Particularly we do not see anything significant at the proposed OT position (K.Y. Huang, GCN 10461). This message can be cited
