A 2 second apparent occultation was recorded by Dave Herald, using a Newtonian Telescope and Watec 910BD camera.
A single frame apparent occultation was recorded by Brian Loader, using an SCT Telescope and Watec 910BD camera.
Three misses were recorded for this event.
There was no updated prediction for this event.
Observers:
1(M) T Barry et al, Linden Observatory, New South Wales, Australia
2 D Herald, Murrumbateman, New South Wales, Australia
3 B Loader, Lake Tekapo, Canterbury, New Zealand
4(M) J Newman, Flynn, Australian Capital Territory, Australia
5(M) H Pavlov, St Clair, New South Wales, Australia
Discussion:
The circle above is plotted at the expected diameter of Chariklo.
Both reported events must be considered doubtful. The discrepancy in reported times shows at least one must be spurious.
Brian's reported event is a single integrated frame.
Dave's reported event is close to a definite miss.
The circle has been plotted central to the various observations.
The figures below show the Tangra light curve of the occultation.
