"Following the detection of the X-ray flash 020903 by HETE (Ricker
et al. GCN Circ. 1530), we have imaged the entire error box with
the 0.6-m (+MOA camera) at Mt. John Observatory in a wide B-
and wide R-band filters (600-s and 1200-s respectively) starting
on Sep 3.5944 UT (i.e. 4.18 hr after the event). Comparison of the
frames with the DSS-2 (R-band) reveals no optical transient down
to the DSS-2 limiting magnitude."
