Thanks Jeremy.
Miguel Montarges is the lead scientist of the Leona-Betelgeuse pro-am campaign and he has just e-mailed the group to mention that they’ve received over 100 observations, and 75 of the light curves are almost not – or not at all – affected by clouds. Recordings were obtained using various filters, so they should be able to measure Betelgeuse’s diameter at a range of wavelengths.
As a very provisional example, Dave Herald measured a light curve obtained in Ha by Alfonso Noschese, and after applying a large limb darkening coefficient it gave a diameter of 60 mas.

The campaign team also hopes that the dataset will detect the huge convection cells in Betelgeuse’s photosphere.
Cheers,
Alex.
