[Original prediction and charts by Edwin Goffin]

[Prediction using OCCULT software]

Edwin Goffin's original prediction indicates an event passing across the north of the North Island of New Zealand and the southeastern tip of Australia.


NEW UPDATE (24 November 1998):

Alex Liu of Exmouth, Western Australia, obtained 16 images of the asteroid alone on November 21 and 22. When reduced against the TAC position of the star these suggest a path somewhat north of Goffin's nominal prediction. The updated track runs across Australia, from approximately Brisbane in the east to Perth in the west. The event time remains in approximate agreement with Goffin, viz:

IMPORTANT NOTE!

Astrometric updates such as these should not be taken as definitive, but rather only as an indication of where the true track may lie relative to the original predicted track. Observers must bear in mind that later astrometry, in which the target star is measured in the same field as the asteroid, may still reveal substantial changes to the predicted track and time of the event. For this reason it is most important that observers far from the predicted track still monitor the event.
