This is a known event, but there hasn't been much publicity about it. The following are predictions
from winOccult for a range of locations in Europe (truncated because of email size limitation on
PlanOccult). It needs a fixed-space font (such as Courier New) to get the columns aligned. The
predictions you have generated are clearly geocentric, where as the predictions below are
topocentric. Note that the ring numbers are the edges of the various rings, with ring 4 and ring 3
defining the Cassini gap. Also ring events that occur when the star is behind Saturn have not been
excluded, and for many locations 'reappearance' events of the star through the ring structure occur
before the occultation by the planet.
The occultation by Saturn will be visible from Europe, Africa and Asia - although South Africa will
get a miss. there are no occultations by the rings after the planetary occultation, but an extensive
passage through the rings before the occultation. That passage will occur at low altitude in Europe,
but will also be visible in Japan and Australia.
I've uploaded into the Files section of the IotaOccultations, and RASNZoccultations, a file of
predictions for the world, and for the Australasian region.
One of the challenges for this event will be in detecting the star. At Mv=7.9, Mp=8.1, the star is
only marginally brighter than Titan (mag 8.4 on that date). Note that the surface brightness of
Titan is about the same as the planet and rings A and B, so I very much doubt that it will be a
spectacular event - and this is why it hasn't been picked up more widely.) Note that passage through
Ring C might be more readily visible, but the star does not pass through Ring C for any location on
the Earth. The greater challenge will be to get a decent recording of the event - and appropriate
filtering might be highly desirable (although I have no idea of what might be appropriate!)
