D. Kuroda (Sokendai), K. Yanagisawa (OAO-NAOJ), and N. Kawai (Tokyo Tech)
report on behalf of a larger collaboration:

The entire error circle of GRB 041016 (=H3578) was observed with the
Tokyo Tech-OAO 50cm telescope equipped with the tricolor camera.  100
frames of 30 s exposure were taken simultaneously in V, R, and I bands
from 13:25 to 14:18 UT.  Visual comparison of the stacked image with
USNO-A2.0 (R) catalog reveals no new source with following upper
limits:

  V: 17.4
  R: 18.5
  I: 18.0.
