The Bordeaux Observatory is an astronomical observatory affiliated with the University of Bordeaux. Built in Floirac, France in 1893 its lenses were focused between +11 and +17 degrees declination. Until 1970 it had taken over 4,000 photographic plates.[1][2] Bordeaux Observatory is home to a large collection of instruments and archives from well over a century of astronomical activities.[3] Until the 2016 it was actively used until the institution moved to a new location at the University.[4]
In the late 19th century an attempt to establish Bordeaux Observatory wad made after the transit of Venus.[5] This lead to a house being set aside as the Bordeaux Observatory, however, it was not equipped with any instruments.[5] Although it did not really get established, it carried the banner of desire for real observatory in the area for a century.[5] Finally, in 1876 an agreement between Government and the city was reached to establish a real observatory.[5] The Government was trying to execute on a national agenda of increased education, and this nexused with city's desire for an Observatory; Bordeaxu would contribute 100,000 francs for its founding.[5]
The Bordeaux observatory was established in the late 1870s, and one of its first instruments was a Meridian circle.[6] The instrument was built by Eichens with and glass objective of 19 cm by Henry.[5] Also, a equatorial mounted refractor (glass lens) with 38 cm lens.[5] The objective lens was made by Merz, and the mounting was done by Gautier and Eichens.[5]
In 1990 a microwave radiometer for measuring ozone was established at the Observatory.[7]
In 1999, Bordeaux Observatory became a site for IVS.[8]
2000s
In early 21st century it remained the site for the Laboratoire d'Astrophysique of Bordeaux, but that institution planned to move out from the site.[3]
In 2016, an astronomer of Bordeaux Observatory noted on a possible formation mechanism for "Planet Nine", a hypothesized planet beyond the Kuiper Belt in the 2010s.[9] In a simulation of solar system formation, they suggested that it could be leftover building block of an earlier time.[9]
As an institution the Bordeaux Observatory became the Observatoire Aquitain des Sciences de l’Univers (OASU).[4] In 2016, they staff moved from Floirac facilites to a new building at the University of Bordeaux in Pessac.[4]
