report on behalf of the MITSuME collaboration:
We observed the field of GRB 130215A (D'Elia et al., GCN 14204)
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 2013-02-15 10:40:36 UT (~9.2 h after the burst).
We detected the previously reported afterglow (Zheng et al., GCNC 14205)
in Rc and Ic bands.
Photometric results and three sigma upper limits of the OT are listed below.
We used GSC2.3 catalog for flux calibration.
