Besides a catalogue of 1.1 billion source positions and broad-band G-magnitudes, this DR1 also includes the positions, G-magnitudes, parallaxes, proper motions for 2 million stars in common between the Tycho-2 Catalogue and Gaia (TGAS). Light curves for 3194 Cepheids and RR Lyrae are also part of the release as well as a special astrometric solution for 2152 ICRF quasars. The goal of this IAU symposium is to ensure the world-wide sharing of the Gaia mission results that will cover the following topics: astrometry and reference frames, Milky Way galaxy and stellar physics and the Solar system bodies. This is the second call for abstract submission and early registration to the IAU symposium. The next close deadlines are: November 1st: IAU grant application December 4: Abstract submission Registration to the symposium are open since beginning of July. We remind you that a limited number of participants will be accepted due to the limited capacity of the conference room.
