Using the unique capabilities of the 1.2m UK Schmidt Telescope (Anglo
Australian Observatory, Siding Spring, Australia), in conjunction with the
6df Spectrograph (set up in straight-through mode), and by simultaneously
monitoring ~100 suitably selected stars at a time, we were able to embark
upon an occultation observation program which yielded ~7,000 hours of
stellar light curves, with ~10 millisecond resolution.
The observation program was conducted over 16 nights during bright of moon
periods in mid 2005. The initial data reduction indicates that we have
captured many events which bear the hallmarks of occultation events, in so
far as the light curves of recorded events typically match that which may be
expected when a small KBO occults a suitable distant star.
Most logged events are spread over many pixels, with 10 pixels
(corresponding to 100 milliseconds) being the typical event duration. By
imultaneously monitoring many stars in the same field, observation
artefacts such as those caused by close-in earth bound objects are readily
eliminated.
It is concluded that the bulk of the events logged are consistent with
events which would be caused by distant sub-kilometre radius KBO's
(typically at ~40AU). Statistical analysis of the reduced data (so far!)
supports this conclusion.
