[Detailed Finder Charts]


Updated:   2013 JUL 05, 16:01 UT

Event Rank : 3

(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.

Chariklo Update Map


On 2013 Aug 22 UT, the 258 km diameter asteroid (10199) Chariklo will occult a 14.6 mag star in the constellation Scorpius for observers along a path across Pacific Ocean.

In the case of an occultation, the combined light of the asteroid and the star will drop by 4.0 mag to 18.6 mag (the magnitude of the asteroid) for at most 25.1 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.
