ASTROMETRIC UPDATE:
OCCULTATION BY (752) SULAMITIS - 2009 JAN 26

[Detailed Finder Charts]


Updated:   2009 JAN 22, 17:43 UT

Event Rank : 75

(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.

Sulamitis Update Map


On 2009 Jan 26 UT, the 63 km diameter asteroid (752) Sulamitis will occult a 13.0 mag star in the constellation Cancer for observers along a path across the north-eastern corner of Tasmania, central Victoria, South Australia, passing near Adelaide and directly over Melbourne.

In the case of an occultation, the combined light of the asteroid and the star will drop by only 0.7 mag to 12.8 mag (the magnitude of the asteroid) for at most 6.3 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: UCAC.
