Terpsichore Update Map


On 2003 Oct 27 UT, the 119 km diameter asteroid (81) Terpsichore will occult a 11.8 mag star in the constellation Sagittarius for observers along a path across Australia from Perth through the centre to Cooktown.

In the case of an occultation, the combined light of the asteroid and the star will drop by 2.5 mag to 14.2 mag (the magnitude of the asteroid) for at most 4.5 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 Stefano Sposetti, historical astrometry from the MPC files (via AstDys), and the following catalogs for the star position: UCAC.
