H. Toda (OAO, NAOJ) and N. Kawai (Tokyo Tech) report on behalf
of the MITSuME collaboration:

We observed the field of GRB 090529 (Sakamoto et al. GCN 9430)
with optical three color (g', Rc and Ic) CCD camera attached to
the MITSuME 50cm telescope of Okayama Astrophysical Observatory.
The observation started on 2009-05-29 14:51:47 UT. We found a
faint source at the UVOT position reported by Schady et al. (GCN
9435) in g' band.

Photometric results are listed below. We used USNO B1 catalog
for flux calibration.
