[Edwin Goffin's Prediction + Finder Charts]

[Detailed Finder Charts]


Updated:   2015 NOV 06, 16:32 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.

Beatrix Update Map


On 2015 Dec 09 UT, the 87 km diameter asteroid (83) Beatrix will occult a 12.2 mag star in the constellation Gemini for observers along a broad path across New Zealand, including most of the North Island, but south of Auckland and north of Wellington, and across Australia, from Maroochydore across southern Queensland and The Northern Territory to c Western Australia near Kalbarri at decreasing elevation.

In the case of an occultation, the combined light of the asteroid and the star will drop by 0.8 mag to 12.3 mag (the magnitude of the asteroid) for at most 11.5 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.
