ASTROMETRIC UPDATE:
OCCULTATION BY (9) METIS - 2006 FEB 11

[Edwin Goffin's Prediction + Finder Charts]

[Detailed Finder Charts]


Updated:   2006 FEB 03, 23:02 UT

Event Rank : 100

(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.

Metis Update Map


On 2006 Feb 11 UT, the 210 km diameter asteroid (9) Metis will occult a 9.7 mag star in the constellation Leo for observers along a path across New Zealand's North Island and the extreme north of the South Island. The shadow then crosses Australia passing directly over Brisbane, the Gold Coast region and Alice Springs. The northern limit of the relatively well defined path runs approximately near Rockhampton and Tennant Creek. The southern limit runs near Grafton and Birdsville.

In the case of an occultation, the combined light of the asteroid and the star will drop by a relatively small 0.7 mag to 9.5 mag (the magnitude of the asteroid) for as long as 24.8 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 following catalogs for the star position: UCAC.
