K. Ayani (Bisei Astronomical Observatory (BAO)) and H. Yamaoka (Kyushu
Univ.) report: 

  We obtained R-band images of the optical afterglow (da Costa, Noel
and Price, GCN 2765) of GRB 041006 (Galassi et al., GCN 2770) with the
BAO 1.01-m reflector.  The observation started on 16:44 UT.  The
stacked image (mean epoch = Oct. 6.71 UT) shows the OT of which a
preliminary R magnitude is about 19.2, compared with the USNO A2.0 red
magnitudes.
