Haute-Provence Observatory The Haute-Provence Observatory (OHP, French: Observatoire de Haute-Provence ) is an astronomical observatory  in the southeast of France, about 90 km east of Avignon and 100 km north of Marseille. It was established in 1937 as a national facility for French astronomers. Astronomical observations began in 1943 using the 1.20 m telescope, and the first research papers based on observations made at the observatory were published in 1944.
