Proceedings of GAIA-FUN-SSO 2014 Third “Gaia Follow-up Network for Solar System Objects” Workshop held at IMCCE/Paris Observatory 2014, November 24 – 26 Institut de mécanique céleste et de calcul des éphémérides Observatoire de Paris Legal Deposite – June 2015 ISBN 2-910015-73-4 Foreword The observation of Solar System Objects (SSO) by the Gaia space astrometry mission will be constrained by a scanning law. Much detection of interesting objects may occur with no possibility of further observations by the probe. These objects will then require complementary ground-based observations. Among them, previously unknown Near- Earth Objects, fast moving towards the Earth or going away from it could be found. Several objects discovered by Gaia could also be Inner-Earth Objects, as the probe will observe at rather low Solar elongations. In order to confirm from the ground the discoveries made in space and to follow interesting targets, a dedicated network is organized, the Gaia Follow-Up Network. This task is performed in the frame of the Coordination Unit 4 of the Gaia Data Processing and Analysis Consortium (DPAC), devoted to data processing of specific objects. The goal of the network is to improve the knowledge of the orbit of poorly observed targets by astrometric observations on alert. This activity is coordinated by a central node interacting with the Gaia data reduction pipeline all along the mission. In 2010 and 2012, we had organized the first two workshops in order to initiate the network and to meet the participants. In 2014, almost one year after the launch of Gaia, we organize the third Gaia-FUN-SSO workshop in Paris in order to discuss further the coordination of the network of observing stations, to discuss the prelaunch training observations which have been performed and to prepare the network for the operating phase of the alert mode which must begin in 2015. During this workshop, the participants had the opportunity to be informed about the status of the Gaia mission, about the alert process for SSO and the ground-based data processing. They were invited to present their activities in relation with this program, or their equipment, instruments and observing sites. Large time slots have been reserved for discussions. This workshop was fruitful and articles have been gathered in these proceedings with the aim to keep track of these very interesting days.
