H. Nakajima, Y. Yatsu, T. Enomoto, K. Kawakami, K. Tokoyoda, T. Ohkawa, and
N. Kawai (Tokyo Tech)  report on behalf of the MITSuME collaboration:

We observed the field of GRB 110213A (D'Elia et al , GCNC 11705)
with the optical three color (g', Rc and Ic) CCD camera attached
to the MITSuME 50cm telescope of Akeno Observatory.
The observation started on 2011-02-13 8:37 UT (~3.3 hours after the burst).
We detected the previously reported afterglow (Cenko et al., GCN 11706)
in all three bands.

Photometric results and are listed below. We used GSC2.3 catalog for
flux calibration.
