Occultation of Chariklo 12th May

The celebrated asteroid 10199 Chariklo (yes, the one with the rings) is due for an occultation on the 12th May, visible from Australia (if the clouds co-operate).

The link for the prediction can be found here:-

Note that the prediction shows the path as being in a line from Perth to Brisbane. This should properly be seen as a prediction rather than a guarantee; it is entirely possible that a person in Alice Springs (or Melbourne) may see the occultation, as the uncertainties are substantial.

The star to be occulted is mag +14.2 so a telescope of reasonable size (8" or better) and an integrating video camera, which can integrate to a couple of seconds, will be needed.

10199 Chariklo is a Centaur, orbiting between Saturn and Uranus. It is the first minor planet known to have rings, which were discovered by occultation methods also.

For further info, talk to your local astro club's occultation person, visit the RASNZ's web page, or discuss here.
