ASTROMETRIC UPDATE:
OCCULTATION BY (29) AMPHITRITE - 2002 APR 01

[Edwin Goffin's Prediction + Finder Charts]


UPDATE: 2002 MAR 23, 05:34 UT

THE UPDATED PATH

Amphitrite Update Map

On 2002 Apr 01 UT (morning of April 2), the 212 km diameter asteroid (29) Amphitrite will occult a 10.5 mag star in the constellation Sagittarius for observers along a path across New South Wales, South Australia and Western Australia.

This is an excellent event, with a very small path uncertainty. The updated path passes very close to SYDNEY as well as across EXMOUTH, WA. The "event rank" (which gives some indication of the likelihood of seeing the event) is 99.

When the occultation occurs the combined light of the asteroid and the star will drop by 1.1 magnitudes to magnitude 11.1 (the magnitude of the asteroid) for at most 8.7 seconds.

This update is based on UNSO/Flagstaff astrometry for the asteroid kindly provided by Ron Stone, TMO astrometry for the asteroid kindly provided by Bill Owen, historical astrometry from AstDys, and the UCAC catalog for the star position.

Additional details of this and other events are available at Steve Preston's website at http://www.oz.net/~stevepr/Asteroids/asteroid.htm

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.
