(Tokyo Tech) report on behalf of the MITSuME collaboration:
We observed the error box of GRB070129 (Godet et al., GCN 6053)
with the 3-color 50cm MITSuME Telescope at Akeno, Japan
starting at 9:44:12 UT, 10.1 hours after the trigger.
In the co-added images of Ic, Rc, and g' bands, we did not detect
the afterglow . The 3-sigma limiting magnitudes based on USNO-B1.0
(I-band) and NOMAD (R-band,g'-band) stars are following.
Filter start time end time Exp(s) Mag (3-sigma upper limit)

Ic 9:44:12 10:22:57 60s * 25 18.4
Rc 9:44:12 10:22:57 60s * 25 19.0
g' 9:44:12 10:22:57 60s * 25 19.4
