H. Nakajima, T. Shimokawabe, Y.A. Mori, Y. Kudou, and N. Kawai (Tokyo
Tech) report on behalf of the MITSuME collaboration:
We performed optical imaging observation of the field of GRB 080905A
(C. Pagani et al. GCN 8180) with the 3-color 50cm MITSuME Telescope at
Akeno, Japan from 12:40:12 UT (42min after the trigger) to 14:32:07 UT.
In the co-added images of Ic, Rc, and g' bands, we did not detect any
afterglow candidate in the XRT error circle. The 3-sigma limiting
magnitudes based on USNO-B1.0 (I-band) and NOMAD (R-band,g'-band)
stars are following:
