[Prediction using OCCULT software + finder charts]

The path given by Occult crosses northern Tasmania just after local sunset and then crosses the northern end of the South Island of New Zealand.


UPDATE: 1 July 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 supplemented with data from the AstDys database. The Hipparcos position of the target star has been used.

Summary:

This updated path lies around 0.3" to the south and 20 seconds earlier. The path now passes just to the south of Tasmania around 8:10 UT with Hobart well within the error tolerance to give a reasonable chance of observing and occultation. Across the Tasman, the path crosses the southern most parts of the South Island at 8:13 UT. Invercargill lies just on the southern edge of the predicted path with Dunedin just north of the northern limit.

Centenaria 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.
