Leda Update Map


NOTE: This update replaces the previous update of July 11.

On 2003 Aug 11 UT, the 115 km diameter asteroid (38) Leda will occult an 11.0 mag star in the constellation Sagittarius for observers along a path across N Australia, Africa.

In the case of an occultation, the combined light of the asteroid and the star will drop by 2.4 mag to 13.2 mag (the magnitude of the asteroid) for at most 10.8 seconds.

This update is based on UNSO/Flagstaff astrometry for the asteroid kindly provided by Ron Stone, astrometry for the asteroid kindly provided by Stepano Sposetti, historical astrometry from 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/
