ASTROMETRIC UPDATE:
OCCULTATION BY (1679) NEVANLINNA - 2005 OCT 27

[Detailed Finder Charts]


Updated:   2005 SEP 25, 18:45 UT

Event Rank : 33

(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.

Nevanlinna Update Map


On 2005 Oct 27 UT, the 51 km diameter asteroid (1679) Nevanlinna will occult a 10.3 mag star in the constellation Monoceros for observers along a path running down the east coast of New Zealand. Although Dunedin is the only city inside the predicted path, the considerable uncertainty means that an occultation could occur anywhere in New Zealand, particularly in the east.

In the case of an occultation, the combined light of the asteroid and the star will drop by 6.4 mag to 16.7 mag (the magnitude of the asteroid) for at most 5.6 seconds.

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.
