The SPM is based on photographic plates taken at our observatory at El Leoncito, Argentina and will yield absolute proper motions and positions to magnitude B 19 for approximately 1 million stars south of declination -20 degrees. The SPM is a joint program between the Yale Southern Observatory and the Universidad Nacional de San Juan, Argentina. The SPM Catalog 2.0 provides positions, absolute proper motions, and photographic BV photometry for over 320,000 stars and galaxies. All objects contained in the SPM 1.0 Catalog (the South Galactic Pole region) are also included in this version. Note that SPM 1.0 has been replaced by SPM 1.1 which has slightly different astrometry (mostly proper motions) due to refinement of the magnitude equation correction in the SPM 2.0 Catalog. The Catalog covers an area of 3700 square degrees in an irregularly bounded band between declinations of -43 and -22 degrees, but excluding fields in the plane of the Milky Way. Stars cover the magnitude range 5 < V < 18.5. The standard errors for the best measured stars are as follows: 20 mas for positions in each coordinate; 2 mas/yr for absolute proper motions and 0.05 mag in B and V bandpasses. In addition to the Catalog, a list of CCD calibrating sequences in BV is provided. It contains 7783 stars. The new feature of the Catalog is an extensive list of cross-identifications with external special catalogs which include all major astrometric catalogs and a large number of astrophysically interesting objects. The Catalog is available on the WWW at http://www.astro.yale.edu/astrom/. Our web-site contains several useful plots showing the sky coverage, error distribution, a quick comparison with the Hipparcos proper motions, etc.
