Kurita, Y. Ono, T. Fujiwara, Y. Yatsu, and N. Kawai (Tokyo Tech) 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.
