ASTROMETRIC UPDATE:
OCCULTATION BY (914) PALISANA - 2008 Nov 14

[Detailed Finder Charts]


Updated:   2008 OCT 30, 14:50 UT

Event Rank : 83

(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.

Palisana Update Map


On 2008 Nov 14 UT, the 81 km diameter asteroid (914) Palisana will occult a 12.9 mag star in the constellation Andromeda for observers along a path across Papua - New Guinea, from Aitape to Merauke, and across Australia from the Gulf of Carpentaria, across Central Australia to Port Lincon in South Australia.

In the case of an occultation, the combined light of the asteroid and the star will drop by 0.5 mag to 12.2 mag (the magnitude of the asteroid) for at most 5.5 seconds.

This update is based on UNSO/Flagstaff astrometry for the asteroid kindly provided by Alice Monet, 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.
