lucky-starLESIA


This page presents the prediction of occultations by selected TNOs and Centaurs for 2018. 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.

As from 25 April 2018, the predictions make use of Gaia DR2 (Gaia Collaboration, 2018) for the positions of the star and the proper motion. Before 25 April 2018, predictions were done with Gaia DR1 (Gaia Collaboration, 2016) for the positions of stars and the Gaia-PS1-SDSS (GPS1) Proper Motion (Tian et al. 2017) and UCAC5 (Zacharias et al. 2017) catalogues for estimated proper motions.

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