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 Jan. 26.68209 19.09 0.05
