[Prediction by Edwin Goffin]

[Prediction using OCCULT software]

The path given by Edwin Goffin covers the western half of Tasmania and the Melbourne metropolitan area. It then runs to the north up the spine of the Cape York Peninsula in Queensland. The path given by Occult lies around two path widths to the east running just east of Hobart in Tasmania and Traralgon in Victoria. It emerges from the Queensland coastline in the Princess Charlotte Bay area.


UPDATE: 12 May 2001

This prediction update has been computed by Steve Preston of the Medina, Washington (state) in the United States based on astrometry from Ron Stone of the US Naval Observatory - Flagstaff Station. The Tycho-2 position of the target star has been used.

Summary:

This updated path lies around four pathwidths to the east of that give by Edwin Goffin with little difference in the expected time. The path now misses Tasmania and crosses the Victorian coastline in the Orbost/Mallacoota area running north to cover much of the Australian Capital Territory (10:49:50 UT) within the eastern part of the path. Running north, the path should lie close to Dubbo before passing into Queensland where it runs along the coastline in the Ingham to Cairns area (10:54 UT).

Brambilla Update

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.
