report:
"We have imaged the entire XRF 040701 error box provided
by HETE-2 (Barraud et al. GCN #2620) with the 0.6-m
telescope (+ MOA camera) at Mt.John Observatory starting
on July 4.459 UT. Observations were performed with the MOA
broad R-band filter with individual exposure times of 300 s.
Visual comparison of the stacked first three images with
the DSS-2 red plate revealed no optical counterpart
candidate brighter than R~20.2."
