Event Rank : 27

(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.

1989DJ Update Map


On 2017 May 11 UT, the 75 km diameter asteroid (6090) 1989 DJ will occult a 11.1 mag star in the constellation Ara for observers along a somewhat uncertain path beginning near Brisbane. The path moves south-west through central NSW, and into western Victoria and South Australia near Adelaide.

In the case of an occultation, the combined light of the asteroid and the star will drop by 5.84 mag to 16.90 mag (the magnitude of the asteroid) for at most 5.0 seconds.

This update is based on, astrometry for the asteroid kindly provided by the IAU Minor Planet Center.
