Laurentia Update Map


On 2003 Sep 26 UT, the 99 km diameter asteroid (162) Laurentia will occult an 11.3 mag star in the constellation Sagittarius for observers along a path slightly east of New Zealand.

In the case of an occultation, the combined light of the asteroid and the star will drop by 3.5 mag to 14.7 mag (the magnitude of the asteroid) for at most 11.6 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 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/
