[Edwin Goffin's Prediction + Finder Charts]

[Detailed Finder Charts]


Updated:   2018 JAN 17, 17:07 UT

Event Rank : 77

(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.

Pamela Update Map


On 2018 Mar 10 UT, the 70 km diameter asteroid (1243) Pamela will occult a 11.1 mag star in the constellation Hydra for observers along a path across Australia, from Canberra across southern New South Wales, central South Australia (north of Port Augusta) and central Western Australia to Dampier.

In the case of an occultation, the combined light of the asteroid and the star will drop by 3.88 mag to 14.90 mag (the magnitude of the asteroid) for at most 9.0 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.
