|Gaia Data Releases|
|General info on Gaia Data Releases can be found here. More specific information on the Gaia's first data release is available here.|
|Main Gaia Archive|
|Gaia data is made available through the Gaia Archive. The Gaia Archive is located at ESAC, Madrid and is under the supervision of the ESA Science Archives Team.|
|Gaia Photometric Science Alerts|
|To browse the Gaia Science Alerts published so far, visit the Photometric Science Alerts website. More information about the alerts is available here.|
|The first Gaia photometric science alert was sent out on 30 August 2014 (see above). Since then, many more were generated to alert the community of the opportunity to observe interesting objects found by Gaia. The latest Gaia photometric science alerts can be found in the feed below.|
|Gaia Follow-Up Network for Solar System Objects|
|The Gaia Follow-Up Network for Solar System Objects (Gaia-FUN-SSO) has been set up in the framework of a task (DU459) of Coordination Unit 4 (Object processing) of the DPAC Gaia consortium. Its goal is to coordinate ground-based observations on alerts triggered by the data processing system during the mission for the confirmation of newly detected moving objects or for the improvement of orbits of some critical targets. Gaia scans the sky following a pre-defined scanning law. Ground-based observations are required to avoid the loss of newly detected Solar System objects and to facilitate their subsequent identification by the probe. The GAIA-FUN-SSO site provides access to solar system object alerts, including the ephemeris to help finding the targets for the registered members of the Gaia Follow-up network.|
|Search for a source in TGAS|
You can now perform a simple search in TGAS using this search widget. More elaborate searches can be performed in the Gaia Archive of course.
|Partner data centres|
In addition to the Gaia Archive, several partner data centres offer access to the Gaia Catalogue. These partner data centres are integrated in CU9, the coordination unit responsible for Catalogue Access. They offer some extra services in coordination with the main Gaia Archive, located at ESAC.
Our partner data centers can be found:
|Preliminary release (23/05/2017): Three stellar positions released to support unique occultation events|
|We released the astrometry for three stars to support the observations of unique occultation events. On 22 June and 23 July 2017 relatively brights stars will be occulted by the largest known centaur Chariklo. Then, on 5 October 2017 an occultation by Neptune's largest satellite, Triton, can be observed. The preliminary Gaia DR2 data for the three stars and more information about these events can be found here.|
