dc.descriptionWe report the discovery of 182 new southern stars with proper motion larger than 0.45''/yr. The stars were found in an expansion of the SUPERBLINK proper motion survey to 8,980 square degrees south of Decl.=-30. The new high proper motion stars include 123 objects with mu>0.5''/yr, and 5 with mu>1.0''/yr. These new stars consist in a variety of nearby red dwarfs and white dwarfs, and (slightly more distant) red halo subdwarf, and are all prime targets for follow-up spectroscopic and astrometric (parallax) observations. Comparison with previous proper motion surveys in the southern sky suggests that SUPERBLINK has a recovery rate between 80% and 90% at southern declinations for stars with red magnitude 10<R<19 and proper motion in the range 0.5<mu<2.0''/yr. This survey makes a significant addition to the census of high proper motion stars at southern declinations.
