report on behalf of the MITSuME collaboration:
We observed the field of GRB 140430A (Siegel et al. , GCN Circular #16190) 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 2014-05-01 10:57:06 UT ( 14.4 h after the burst).
We did not find any new point source within the enhanced XRT circle (Evans et al., GCNC 16195) in all the three bands.
The measured magnitudes were listed below.
