report on behalf of the MITSuME collaboration:
We observed the field of GRB 140515A (P.D'Avanzo et al., GCN Circular #16267) with the
optical three color (g, Rc, and Ic) CCD cameras attached to the MITSuME 50 cm
telescope of Akeno Observatory, Yamanashi, Japan.
The observation started on 2014-05-15 10:32:10 UT ( 1.3h after the burst).
We did not find any new point source within the enhanced XRT circle
in all the three bands.The measured magnitudes were listed below.
