The recording of the meeting discussing the presentation [0] notes three issues with occlusions by Leona:
1. There is uncertainty with regard to the path, i.e. exactly where will it be projected on the surface of the Earth.
2. Size of Leona is uncertain, hence the expected magnitude of the decrease in brightness of Betelgeuse as a result of occultation was uncertain. A bigger decrease means that it's easier to get the public involved in observing.
3. The group looking at this is doing citizen science. They need to know the above in order to decide how much to involve public because this is something where if the above is known, then the public can participate with DSLR cameras and record light curves suitable for astronometric analysis.
