R. Iizuka and S. Maeno report on behalf of NHAO.

We observed the field of GRB 071011 (GCN 6882) with MINT
on the 2.0-m NAYUTA telescope at Nishi-Harima Astronomical
Observatory, Japan. We took images for a total of 3000 sec in
R-band filter on 2007 Oct 11 13:36 UT (56 minutes after the burst).

We detect the afterglow reported by GCN 6883 (Daniel Parley et al.).
We estimate a preliminary magnitude of R~22 mag relative to
USNO-B1.0 stars.
