ASTROMETRIC UPDATE:
OCCULTATION BY (1502) ARENDA - 2015 Dec 26

[Detailed Finder Charts]


Updated:   2015 JUL 12, 13:11 UT

Event Rank : 56

(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.

Arenda Update Map


On 2015 Dec 26 UT, the 32 km diameter asteroid (1502) Arenda will occult a 7.1 mag star in the constellation Gemini for observers along a narrow path across central New Zealand, including Wellington, Blenheim and Westport, and passing just south of Tasmania, with Hobart within the one sigma limit.

In the case of an occultation, the combined light of the asteroid and the star will drop by 7.6 mag to 14.7 mag (the magnitude of the asteroid) for at most 3.1 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: .
