  The Côte d'Azur Observatory (French: Observatoire de la Côte d'Azur, OCA) is a network of astronomical observatories throughout southern France. It originated in 1988 with the merger of two observatories:
  
  * Nice Observatory
  * Centre de recherches en géodynamique et astrométrie (CERGA)
  
  Cote d'Azure Observatory tested beam combining technology at CHARA array.
  
  Astronomers developed a theory about M-Type asteroids, that may be tested by the planned spacecraft Psyche.
