International Occultation Timing Association / European Section e.V.
Predictions of trans-Netpunian objects (TNOs), Cubewanos and Centaurs by the Lucky Star project. The ERC project Lucky Star’s aim is to study the solar system beyond Neptune with stellar occultations. The project is led by Bruno Sicardy in collaboration with groups from Paris, Meudon, Granada and Rio.
