report on behalf of the KANATA GRB team:
We took optical and IR images of the field of GRB070419A (GCN 6302) at
11:01-11:12 UT 19 Apr. using TRISPEC attached to the KANATA
1.5-m telescope at Higashi-Hiroshima Observatory, Japan.
We obtained 10 sets of V, J, and Ks-band images with a 63, 60,
and 48-s exposure times under thin clouds.
No new object was significantly detected in the combined image
(19.46322 Apr. 2007 UT). Limit magnitudes are 20.0, 17.2, and 15.0 mag
in V-, J-, and Ks-band, respectively, using the USNO A2.0 and
2MASS catalog.
