Descripción
The Real Instituto y Observatorio de la Armada (ROA) meridian circle was moved to the Estación de Altura Carlos Ulrrico Cesco in the República Argentina in 1996. Until November 1999 the observations were carried out with a moving slit micrometer. In spring 2001 the result of these observations has been published, forming the first Hispano-Argentinian Meridian Catalogue (HAMC). In December 1999 was installed a SpectraSource CCD camera of 1552×1024 pixels of 9 μ. The CCD camera observes in drift scan mode. A survey of the southern hemisphere is being observed from +3° to -60° of declination. In this contribution is presented a description of the telescope and the automatic control system, the results of observations carried out with the slit micrometer, and the observational and preliminary reduction techniques with the CCD camera, the present state of the southern hemisphere survey and the future possibilities.
