M. Uemura, A. Arai, and T. Uehara (Hiroshima Univ.), 
report on behalf of the KANATA GRB team:

  We took optical CCD images of the field of GRB070125 (GCN 6024) 
during 16:11-16:32 UT 26 Jan. using the TRISPEC attached to the KANATA 
1.5-m telescope at Higashi-Hiroshima Observatory, Japan.  
We obtained 10 R-band images with a 123-s exposure time.  
Using the same comparison star used in Xing et al. (GCN 6035; R=15.2), 
our data reduction yielded the following result:

UT             R mag  err
