The Tartu Observatory (Estonian: Tartu Observatoorium) is the largest astronomical observatory in Estonia. On 1 January 2018, Tartu Observatory was joined again to the University of Tartu, and the observatory is now an institute of the university. It is located on the Tõravere hill, about 20 km south-west of Tartu in Nõo Parish, Tartu County. The old Tartu Observatory, located in Tartu city centre, is known internationally for its connection to Friedrich Georg Wilhelm von Struve and the Struve Geodetic Arc, of which it is the first reference point.[1][2][3]

History

The Tartu Observatory was founded at the

refractor arrived, the largest achromatic telescope in the world at the time. When von Struve began assembling his Geodetic Arc
in 1816, the doorstep of the observatory became its first point.

In 1946 the renamed Tartu Observatory was separated from the university and subjected to the

reflector telescope had first light
. In 1964, an international conference was held and the Tartu Observatory was renamed von Struve Observatory. In 1974 the 1.5 metre telescope become operational. The name of the observatory was reverted to Tartu Observatory in 1995. In 1998, a 0.6 metre reflector and in 2013, a 0.3 metre modern robotic telescope were installed.

The old observatory building now mainly serves as a museum and is a part of a public science education centre.

Several notable scientists have been associated with the Tartu Observatory:

Ernst Julius Öpik, Grigori Kuzmin, Jaan Einasto
.

Equipment

The observatory has three main telescopes. The 1.5 metre

spectroscopic observations. The second and third telescope are a 0.6 metre and 0.31 metre reflectors for photometric observations. There is also a pitch for a collection of meteorological instruments
on the observatory grounds.

Tartu Observatory has also laboratories for accurate radiometric calibration for near-UV to shortwave infrared radiation; vacuum-, vibration-, temperature, and electromagnetic compatibility testing.
