The CERGA Observatory (French: Centre de recherches en géodynamique et astrométrie, pronounced [sɑ̃tʁ də ʁəʃɛʁʃ ɑ̃ ʒeɔdinamik e astʁɔmetʁi]; obs.

code: 010) was a scientific department and astronomical station of the Côte d'Azur Observatory in southern France, where several asteroids were discovered during 1984–1993.

[1][2] CERGA included 28 researchers and as many engineers and technicians located on the Observatory sites of Nice, Grasse and Calern (Caussols).

The scientific activities covered fields as diverse as fundamental astronomy, celestial mechanics, and space geodesy.

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.
