ASTROMETRIC UPDATE:
OCCULTATION BY (1576) FABIOLA - 2015 OCT 30

[Detailed Finder Charts]


Updated:   2015 Sep 16, 03:06 UT

Event Rank : 30

(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.

Fabiola Update Map


On 2015 Oct 30 UT, the 26 km diameter asteroid (1576) Fabiola will occult a 10.1 mag star in the constellation Taurus for observers along a path across southern Queensland, northern New South Wales, central South Australia and southern West Australia, passing near Brisbane, Toowoomba and Ceduna.

In the case of an occultation, the combined light of the asteroid and the star will drop by 1.1 mag to 15.8 mag (the magnitude of the asteroid) for at most 10.8 seconds. Note waning gibbous moon very nearby.

This update is based on UNSO/Flagstaff astrometry for the asteroid kindly provided by Hugh Harris, historical astrometry from the MPC files (via AstDys), and the following catalogs for the star position: UCAC.
