"Following the detection of the X-ray flash 030723 by
HETE-2, we have imaged the entire error box with the
0.6-m telescope (+MOA camera) at Mt. John Observatory
in wide R- and B-band filters (3 x 300-s each) starting
on July 23.59 UT (i.e. 7.6 hr after the event).
Comparison of a single R-band frame with the DSS-2 (R-
-band) reveals no optical transient down to the DSS-2
limiting magnitude."
