Hedda Update Map


On 2003 Sep 14 UT, the 58 km diameter asteroid (207) Hedda will occult a 11.9 mag star in the constellation Pisces for observers along a path across northern Australia.

In the case of an occultation, the combined light of the asteroid and the star will drop by 1.2 mag to 12.7 mag (the magnitude of the asteroid) for at most 5.7 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 UCAC catalog for the star position.

Additional details of this and other events are available at Steve Preston's website at http://www.asteroidoccultation.com/
