Metcalfia Update Map


On 2003 Nov 16 UT, the 60 km diameter asteroid (792) Metcalfia will occult a 11.2 mag star in the constellation Gemini for observers along a path across Australia from Cairns through the Simpson Desert and exiting at the Southern coast on the WA/SA border..

In the case of an occultation, the combined light of the asteroid and the star will drop by 2.7 mag to 13.8 mag (the magnitude of the asteroid) for at most 14.3 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, historical astrometry from the MPC files (via AstDys), and the following catalogs for the star position: UCAC.
