Telescope Joan Oró obtains the Gaia-OSA certificate
The telescope Joan Oró (TJO) of the Montsec Astronomical Observatory, has recently received the official certificate of collaboration with Gaia-OSA (Groundbased Observational Service for Asteroids), as the telescope that more data has provided to this asteroid observation network campaign.


Gaia-OSA is a platform to coordinate observations of asteroid light curves involving both professional and amateur observatories. The interactive application, which can be accessed online (, lets you know what objects are most interesting on a given night and at what time they will also be observed by Gaia mission. The same platform is also responsible for making data processing.


Observations of the full curve of the asteroid 1453 Fennia by TJO.

Coordination in this type of observations allows for very detailed information of the rotation and shape of asteroids from continuous photometric measurements. Furthermore, the combination with measurements by the Gaia mission simultaneously calibrates measurements from land, especially when the light curve is complex. So far, the TJO has supplied more than 20 sets of measures, making it the most active within the Gaia-OSA network observatory.
