On 25 April 2018 ESA’s Gaia Data Processing and Analysis Consortium published the second release of the mission data products (known as Data Release 2, or DR2 for short). For the first time, Gaia astrometry of more than 14 000 known asteroids was made public, showing that the spacecraft can achieve astrometric precisions at the milliarcsecond level.

Two large objects have been observed in the month ofJuly. (85989) 1999 JD6 had a distant encounter with the Earth, while the newly discovered asteroid 2015 OL35 entered our priority list for follow-up observations.

We took the opportunity of the ExoMars 2016 launch to organize a ground-based observational campaign.
