M. Yoshida, K. Yanagisawa, Kuroda, D., Y. Shimizu, S. Nagayama,
Toda, H. (OAO, NAOJ) and N. Kawai (Tokyo Tech) report on behalf
of the MITSuME collaboration:
We performed optical imaging observation (g', Rc, and Ic) of the
field of GRB 080613A (Gotz et al. GCN 7871) with 50cm MITSuME
telescope at Okayama Astrophysical Observatory from 13:44:35 UT
(4h 9m after the trigger) to UT 15:13:05 on June 13 2008.
We found no new source within a 10 arcsec radius of the position
of the optical afterglow candidate reported by Guidorzi et al.
(GCN 7872). Three sigma limiting magnitudes of our observation
are listed below.
