A welcome evening is organized on wednesday november 15th, starting from 5:30 p.m.

A workshop will be held in Paris on November 15-18, 2006. It is organised by the Institut de Mécanique Céleste et de Calcul des Éphémérides (IMCCE - CNRS UMR 8028 - Paris Observatory - Université Pierre et Marie Curie UFR924).

This workshop is mainly dedicated to astrometry and photometry of Solar System objects events and to the preparation of future campaigns of observation. Several astronomical studies require a large network of observers in order to acquire enough data of rare phenomena or to observe objects on alert or for a follow-up.

This workshop will especially focus on two specific projects :

The setting-up of networks dedicated to these purposes will be especially discussed. We intend to offer the opportunity to exchange experiences, to prepare new observations, to discuss the methods, techniques and objectives. This workshop will be the opportunity to create or reinforce the links between the observers.

Key words : Natural satellites-Mutual events-Space astrometry-GAIA-Science alerts-Asteroids-Near Earth Objects-Multiple asteroids-Stellar occultations.
