report:

We have performed further analyses of HETE triggers H4043 and H4044, in
conjunction with a similar event (H4047).  We have concluded that these
events are not in fact due to a previously unknown cosmic source.  They are
instead due to SCO-X1, in conjunction with episodes of loss of spacecraft
attitude control that can occur sporadically near the daytime terminator.

We regret the confusion created by this error.
