Lilliana Update Map


On 2003 Oct 10 UT, the 71 km diameter asteroid (756) Lilliana will occult a 6.9 mag star in the constellation Taurus for observers along a path across Australia.

In the case of an occultation, the combined light of the asteroid and the star will drop by 8.7 mag to 15.6 mag (the magnitude of the asteroid) for at most 5.5 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, historical astrometry from the MPC files (via AstDys), and the following catalogs for the star position: Hipparcos , Tycho-2.
