ASTROMETRIC UPDATE:
OCCULTATION BY (654) ZELINDA - 2013 JUN 06

[Edwin Goffin's Prediction + Finder Charts]

[Detailed Finder Charts]


Updated:   2013 Apr 17, 18:06 UT

Event Rank : 99

(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.

Zelinda Update Map


On 2013 Jun 06 UT, the 124 km diameter asteroid (654) Zelinda will occult a 12.1 mag star in the constellation Lupus for observers along a path across New Zealand, passing over Auckland and across Australia, running from Lismore in northern New South Wales, across Queensland and Northern Territory to Cobourg Peninsula.

In the case of an occultation, the combined light of the asteroid and the star will drop by only 0.6 mag to 11.8 mag (the magnitude of the asteroid) for at most 10.2 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: UCAC.

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