Scientific paper

The Southern Supercluster is described using data compiled from five catalogs, reduced to a homogeneous system following RC2. In terms of mass, luminosity, and mass-to-light ratio, the Southern Supercluster compares well with the Coma and Hercules superclusters, but is less massive than the Local Supercluster. It is shown that, even though the Southern Supercluster is the nearest supercluster to the Local Supercluster, it is well separated from the Local Supercluster. However, there is evidence of a tenuous stream of galaxies connecting the Southern Supercluster with the Perseus Supercluster.
