ASTROMETRIC UPDATE:
OCCULTATION BY (97) KLOTHO - 2006 OCT 31

[Detailed Finder Charts]


Updated:   2006 OCT 03, 04:14 UT

Event Rank : 84

(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.

Klotho Update Map


On 2006 Oct 31 UT, the 83 km diameter asteroid (97) Klotho will occult a 11.8 mag star in the constellation Orion for observers along a wide path across Western Australia and South Australia.

In the case of an occultation, the combined light of the asteroid and the star will drop by only 0.4 mag to 10.8 mag (the magnitude of the asteroid) for at most 12.6 seconds. This event may be not detectable visually.

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.

Additional details of this and other events are available at Steve Preston's website at http://www.asteroidoccultation.com/
