Protogeneia Update Map


On 2003 Sep 10 UT, the 132 km diameter asteroid (147) Protogeneia will occult a 9.8 mag star in the constellation Aquarius for observers along a path across Nicaragua and eastern Australia.

In the case of an occultation, the combined light of the asteroid and the star will drop by 3.4 mag to 13.1 mag (the magnitude of the asteroid) for at most 17.3 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, astrometry for the asteroid kindly provided by Gordon Garradd, historical astrometry from the MPC files (via AstDys), and the UCAC catalog for the star position.
