We are observing the error circle of GRB021004 obtained by HETE-2
(Shirasaki et al. GCN 1565) with the Bisei Astronomical Observatory (BAO)
1.01-m telescope. We have confirmed the optical transient reported by
Fox (GCN 1564). The R-magnitude was about 16.0 at Oct. 4 14:13 UT. The
observation and more accurate photometry are in progress.
