Gaia-GOSA: An interactive service for coordination of asteroid observation campaigns

We present the Gaia-Groundbased Observational Service for Asteroids (GOSA). Gaia-GOSA is an interactive tool which supports observers in planning photometric observations of asteroids. Each user is able to personalise the observation plan taking into account the equipment used and the observation site. The list of targets has been previously selected among the most relevant and scientifically remarkable objects, while the prediction of the transits in the Gaia’s field of view have been calculated at the Observatoire de la C^ote d’Azur. The data collected by the GOSA community will be exploited to enhance the reliability of the Gaia’s Solar system science. The service is publicly available at www.gaiagosa.eu.
