K. Yanagisawa (OAO/NAOJ), Y. Yatsu, and N. Kawai (Tokyo Tech) report
on behalf of the Mitsume collaboration:
"We have observed the field of GRB 060105 (Ziaeepour et al. GCN 4429)
with the three-color Mitsume 50 cm telescopes at Okayama and Akeno,
Japan starting at 9:14 UT (2.4 hours after the burst).
The summary of the observations is following:
Telescope bands time (UT) exposure
--------- ---------- ---------------- ------------
Okayama g', Rc, Ic 09:14 - 09:41 UT 60 s x 20
Akeno V, Rc, Ic 09:32 - 11:20 UT 30 s x 158
--------- ---------- ---------------- ------------
Comparison with the DSS-2R image does not reveal an OT at the position
of the XRT error circle.
The 10-sigma upper limit magnitudes for the Okayama images are
g': 17.1
Rc: 17.3
Ic: 17.5
