ASTROMETRIC UPDATE:
OCCULTATION BY (478) TERGESTE - 2001 NOVEMBER 8

[Prediction using OCCULT software + finder charts]

The prediction given by OCCULT ran from the Brisbane/Gold Coast area of southern Queensland southwest across central New South Wales and western Victoria.


UPDATE: 4 November 2001

THE UPDATED PATH

Tergeste Update

This update has moved the path southeast by around 1.5 path widths relative to that given by Occult and around 10 seconds earlier. The path crosses the southern Coral Sea to the northern New South Wales coastline in the Grafton/Port Macquarie area. (13:38:30 UT). Running on to the southwest, the path includes Tamworth, Bathurst and Albury before crossing metropolitan Melbourne at 13:39:30 UT. Canberra, Sydney and Brisbane all lie well within the error margin of this calculation and (given cooperative weather), the section has observers located such that it will be virtually impossible for the shadow to slip through this net !!

The target star is the eastern and fainter component of a pair - a magnitude 9.9 star lies 1 minute of arc to the west.

Calculation Source

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

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.
