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.

Davida Update Map


On 2016 Aug 05 UT, the 291 km diameter asteroid (511) Davida will occult a 11.0 mag star in the constellation Libra for observers along a path passing near Canberra and ending in eastern Victoria.

In the case of an occultation, the combined light of the asteroid and the star will drop by 1.85 mag to 12.60 mag (the magnitude of the asteroid) for at most 28.2 seconds.

This update is based on UNSO/Flagstaff astrometry for the asteroid kindly provided by Hugh Harris, astrometry for the asteroid kindly provided by Bill Owen, astrometry for the asteroid kindly provided by the IAU Minor Planet Center.
