Gaia-GOSA: A Collaborative Service for Asteroid Observers

Abstract

We describe the Gaia-Ground-based Observational Service for Asteroids (Gaia-GOSA), which is a website aiming to facilitate asteroid observers in contributing to the Gaia mission by gathering lightcurves of selected targets. GOSA users can plan their observing runs by selecting the visible targets for a given date, collaborate with other observers and upload the frames obtained. OA UAM team will analyze the data, publish the results in the website, and create a lightcurve catalog. Once calibrated, lightcurves will be easily included in the analysis of Gaia data, which will allow us to enhance the determination of asteroids' physical properties.
