A 9 second occultation, with ring events, was recorded by Steve Kerr, using an SCT Telescope and Watec 910BD camera.
A 12 second occultation was recorded by Blair Lade and Andrew Cool, using an SCT Telescope and CCD model QHY5L11 camera.
Two misses were recorded for this event.
There was no updated prediction for this event.
Observers:
1(M) D Gault, Hawkesbury Heights, New South Wales, Australia
2 S Kerr, Rockhampton, Queensland, Australia -ring event
3 S Kerr, Rockhampton, Queensland, Australia
4 S Kerr, Rockhampton, Queensland, Australia -ring event
5 B Lade & A Cool, Modbury Heights, South Australia, Australia
6(M) J Broughton, Reedy Creek, Queensland, Australia
Discussion:
The circle above is plotted at the expected diameter of Chariklo. The circle has been plotted to fit the observed chords.
Neither Dave nor John was close enough to the actual path to observe ring events, even if their gear was capable of it.
The figures below show the Tangra light curve of the occultation.

My camera isn't sensitive enough for high-cadence video at 14th magnitude for imaging ring disappearances though.
