"We have imaged entire error region of GRB051109B(Tagliaferri et
al. GCN 4222, Swift trigger=163170) using Kiso 1.05m Schmidt
telescope. After end of twilight, we have started B and R band
observations at 09:12:07 (UT). Comparison with DSS images and USNO-B
catalog, there is no new source brighter than B=20.9, R=20.2. There is
also no significant signals at the UVOT position reported by
Tagliaferri et al (GCN 4222).
