ASTROMETRIC UPDATE:
OCCULTATION BY (482) PETRINA - 2002 OCT 24

[Edwin Goffin's Prediction + Finder Charts]


UPDATE: 2002 SEP 30, 22:28 UT

THE UPDATED PATH

Petrina Update Map

On the evening of 2002 Oct 24 UT, the 46 km diameter asteroid (482) Petrina will occult a 11.8 mag star in the constellation Capricornus for observers along a path across SE Australia, New Zealand.

In the case of an occultation, the combined light of the asteroid and the star will drop by 2.2 mag to 13.9 mag (the magnitude of the asteroid) for at most 2.9 seconds.

This update is based on UNSO/Flagstaff astrometry for the asteroid kindly provided by Ron Stone, historical astrometry from AstDys, and the following catalogs for the star position: UCAC, Tycho-2.

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.
