OCA-DLR Asteroid Survey (O.D.A.S.)

O.D.A.S. is a dedicated programme to search for asteroids and comets, with special emphasis on NEO's within the framework of the EUNEASO project, in cooperation and support of global efforts in NEO-research, initiated by the WGNEO of the IAU, and the Spaceguard Foundation. It is operated at the 90cm Schmidt-telescope of the OCA at Calern, north of Nice, in southern France, as a joint venture between the OCA - Observatoire de la Côte d'Azur, Nice, France and the DLR - Institute of Planetary Research, Berlin-Adlershof, Germany. The current system uses a 2k CCD camera in combination with an automated asteroid detection software package.

O.D.A.S. began observations in October 1996 and observes for about 15 nights each month using the weeks of first and last quarter of the Moon. Discoveries are reported to the Minor Planet Center, whose NEO Confirmation Page contains newly discovered objects which require confirmation by further observations.


Since April 1999 the O.D.A.S. observing programme has been discontinued.
