ASTROMETRIC UPDATE:
OCCULTATION BY (5875) KUGA - 2013 APR 09

[Detailed Finder Charts]


Updated:   2013 Mar 16, 14:05 UT

Event Rank : 10

(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.

Kuga Update Map


On 2013 Apr 09 UT, the 12 km diameter asteroid (5875) Kuga will occult a 10.4 mag star in the constellation Hydra for observers along a narrow, large uncertainty path across the Northland region of New Zealand, then across Australia, beginning near Batemans Bay, running across southern New South Wales, passing over Canberra, running across northern Victoria, southern South Australia, passing over Adelaide and finally across south-western West Australia, leaving near Dongarra, north of Perth.

In the case of an occultation, the combined light of the asteroid and the star will drop by 5.3 mag to 15.7 mag (the magnitude of the asteroid) for at most 1.2 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.
