Updated:   2014 Mar 12, 00:05 UT

Event Rank : 65

(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.

ITA Update Map


On 2014 Apr 30 UT, the 66 km diameter asteroid (1735) ITA will occult a 10.7 mag star in the constellation Corona Australis for observers along a path across Northern Territory, eastern South Australia, western Victoria and western Tasmania, passing over Horsham and Warrnambool.

In the case of an occultation, the combined light of the asteroid and the star will drop by 3.6 mag to 14.2 mag (the magnitude of the asteroid) for at most 7.3 seconds.

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.

Additional details of this and other events are available at Steve Preston's website at http://www.asteroidoccultation.com/
