Caia Update Map


On 2004 Dec 18 UT, the 82 km diameter asteroid (952) Caia will occult a 11.9 mag star in the constellation Aries for observers along a path across New Zealand.

In the case of an occultation, the combined light of the asteroid and the star will drop by 1.4 mag to 12.9 mag (the magnitude of the asteroid) for at most 15.6 seconds.

This update is based on UNSO/Flagstaff astrometry for the asteroid kindly provided by Ron Stone, historical astrometry from the MPC files (via AstDys), and the following catalogs for the star position: UCAC.
