Annotation

Aims. Astrometric observations performed by the Gaia Follow-Up Network for Solar System Objects (Gaia-FUN-SSO) play a key role in ensuringthat moving objects ﬁrst detected by ESA?s Gaia mission remain recoverable after their discovery. An observation campaign on the potentiallyhazardous asteroid (99 942) Apophis was conducted during the asteroid?s latest period of visibility, from 12/21/2012 to 5/2/2013, to test the coordination and evaluate the overall performance of the Gaia-FUN-SSO. Methods. The 2732 high quality astrometric observations acquired during the Gaia-FUN-SSO campaign were reduced with the Platform for Reduction of Astronomical Images Automatically (PRAIA), using the USNO CCD Astrograph Catalogue 4 (UCAC4) as a reference. The astro- metric reduction process and the precision of the newly obtained measurements are discussed.We compare the residuals of astrometric observations that we obtained using this reduction process to data sets that were individually reduced by..
