ASTROMETRIC UPDATE:
OCCULTATION BY (1727) METTE - 2008 JAN 04

[Detailed Finder Charts]


Updated:   2008 JAN 02, 23:02 UT

Event Rank : 25

(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.

Mette Update Map


On 2008 Jan 04 UT, the 10 km diameter asteroid (1727) Mette will occult a 7.8 mag star in the constellation Hydra for observers along a narrow path across central Western Australia.

In the case of an occultation, the combined light of the asteroid and the star will drop by 6.4 mag to 14.2 mag (the magnitude of the asteroid) for at most only 1.2 seconds.

This update is based on UNSO/Flagstaff astrometry for the asteroid kindly provided by Alice Monet, historical astrometry from the MPC files (via AstDys), and the following catalogs for the star position: .
