report on behalf of the MITSuME collaboration:
We observed the field of GRB 110102A (Oates et al., GCN 11509)
with the optical three color (g', Rc and Ic) CCD camera attached
to the MITSuME 50cm telescope of Okayama Astrophysical Observatory.
The observation started on 2011-01-02 20:08:45 UT (~1.3 hours after
the burst). We detected the afterglow candidate within the
enhanced XRT error circle (Goad et al., GCNC 11510) in all the three
bands.
Photometric results are listed below. We used SDSS catalog for flux
calibration.
