Haute-Provence Observatory (Observatoire de Haute-Provence)
Haute-Provence Observatory (Observatoire de Haute-Provence) is a French national facility, established in 1937 and operated by the Centre National de la Recherche Scientifique (CNRS). It is built on a plateau, 645 meters (2,100 feet) above sea level, at Saint-Michel in southern France, about 95 kilometers (60 miles) north of Marseilles. Among its instruments are reflecting telescopes with apertures of 1.93 meters (76 inches), 1.52 meters (60 inches), 1.2 meters (47 inches), and 80 centimeters (36 inches), and a 60/90-centimeters (24/36-inches) Schmidt camera. Attached to the 1.93-meter telescope is the Elodie spectrograph used to search for extrasolar planets.
