The link above provides ongoing observational campaigns of occultations that takes into account the most accurate ephemerides as determined by Rio-Paris-Spain teams.

The link above provides predictions of stellar occultations by TNOs and Centaurs, as part of the efforts led by the Observatório Nacional/MCTIC and the Laboratório Interinstitucional de e-Astronomia (P.I’s.: R. Vieira-Martins and L. da Costa, Brazil), the Paris Observatory (ERC “Lucky Star” project, P.I.: B. Sicardy, France), and the Instituto de Astrofísica de Andalucía (P.I.: J.-L. Ortiz, Spain). All objects considered here are those listed by the Johnston’s Archive, as last updated on 2016/SEP/05. Exception is made to Pluto and those objects that are presented as not having an MPC designation.
These maps are intended to provide a useful step to select those events on which a more careful work to refine their predictions is considered to be of interest. More accurate predictions to a smaller number of objects, as well as details on observational procedures and hints to observe an occultation event, can be obtained at the Lucky Star page by J. Desmars and at F. Braga-Ribas’ page.
Please, read the ReadMe file for details on the page and its contents.
Please, if you plan to observe one of these occultation events, contact Julio Camargo or F. Braga-Ribas
