Olga Update Map


On 2004 Sep 28 UT, the 67 km diameter asteroid (304) Olga will occult a 11.5 mag star in the constellation Capricornus for observers along a path across SE Asia, Australia.

In the case of an occultation, the combined light of the asteroid and the star will drop by 1.6 mag to 12.8 mag (the magnitude of the asteroid) for at most 6.6 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 the MPC files (via AstDys), and the following catalogs for the star position: UCAC.

Additional details of this and other events are available at Steve Preston's website at http://www.asteroidoccultation.com/
