report on behalf of MITSuME collaboration:

We observed the field of GRB 140215A (Markwardt et al., GCNC 15837)
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 2014-02-15 10:03:22 UT (~5.9 h after the burst).
We detected the previously reported afterglow (Markwardt et al., GCNC 15837;
Cenko et al., GCNC 15838) in Rc and Ic bands.

Photometric results and three sigma upper limit of the OT are listed below.
We used GSC2.3 catalog for flux calibration.
