This page presents the prediction of occultations by selected TNOs and Centaurs for 2017. These predictions are made in the framework of Lucky Star project (led by B. Sicardy) and in collaboration with groups from Paris, Meudon, Granada and Rio. Information about the predictions can be found in Assafin et al. (2010) for Pluto system predictions, Assafin et al. (2012) for the TNO predictions, Camargo et al. (2014) for TNO and Centaur predictions. Ephemerides of the selected objects come from Desmars et al. (2015) and they are regularly updated thanks to observations from Minor Planet Center and our own observations made at ESO, Pic du Midi, Calar Alto, Sierra Nevada and Observatorio do Pico dos Dias. Predictions make use of Gaia DR1 (Gaia Collaboration, 2016) for the positions of stars.

For three very specific occultations occurring this year, the Gaia team has provided position, proper motion and parallax with the release of three preliminary Gaia DR2 stellar positions. The events are for Chariklo on 22 June 2017 and 23 July 2017, and for Triton on 5 October 2017.

IMPORTANT: If you plan to observe one of these predicted events, please contact J. Desmars .
