ASTROMETRIC UPDATE:
OCCULTATION BY (467) LAURA - 2007 Mar 18

[Detailed Finder Charts]


Updated:   2007 MAR 09, 23:39 UT

Event Rank : 56

(The event Rank is a measure of the likelihood of observing an event, and is equal to the probability of at least one successful observation by a team of two observers spaced 1/8 path width just inside opposite sides of the predicted path. An event rank of 100 indicates that the prediction is expected to be very accurate).


THE UPDATED PATH

Note: The duration given in the line below is the interval during which the occultation shadow sweeps across the Earth - please see the minute markers on the map to determine the approximate time for your location.

Laura Update Map


On 2007 Mar 18 UT, the 42 km diameter asteroid (467) Laura will occult a 12.0 mag star in the constellation Gemini for observers along a path just south-west of Australia.

In the case of an occultation, the combined light of the asteroid and the star will drop by 3.7 mag to 15.6 mag (the magnitude of the asteroid) for at most 4.3 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.
