The **CERGA Observatory** (French: *Centre de recherches en géodynamique et astrométrie*, sɑ̃tʁ də ʁəʃɛʁʃ ɑ̃ ʒeɔdinamik e astʁɔmetʁi; [obs. code](/source/List_of_observatory_codes): [010](/source/IAU_code#010)) was a scientific department and astronomical station of the [Côte d'Azur Observatory](/source/C%C3%B4te_d'Azur_Observatory) in southern France, where several [asteroids](/source/Asteroid) were discovered during 1984–1993.[1][2]

## Description

CERGA included 28 researchers and as many engineers and technicians located on the Observatory sites of [Nice](/source/Nice), [Grasse](/source/Grasse) and [Calern](/source/Calern) ([Caussols](/source/Caussols,_Alpes-Maritimes)). The scientific activities covered fields as diverse as fundamental [astronomy](/source/Astronomy), [celestial mechanics](/source/Celestial_mechanics), and space [geodesy](/source/Geodesy). CERGA was in charge of several observing facilities of the [Lunar Laser Ranging experiment](/source/Lunar_Laser_Ranging_experiment), for example, the lunar-laser ranging telescope and the two satellite laser stations.

By nature the scientific activity involved the acquisition of data and their processing, a dedicated instrumental development and a close relationship with the more theoretical aspects in dynamics and observation modelling.

CERGA was dissolved in 2004 when the parent [Côte d'Azur Observatory](/source/C%C3%B4te_d'Azur_Observatory) re-organized. The main-belt asteroid [2252 CERGA](/source/2252_CERGA) was named for the observatory, where this asteroid was discovered by [Kōichirō Tomita](/source/K%C5%8Dichir%C5%8D_Tomita).[2]
