J/AJ/142/92 New proper motion stars with pm>=0.18"/yr (Boyd+, 2011) ================================================================================ The solar neighborhood. XXVII. Discovery of new proper motion stars with {mu} >= 0.18"/yr in the southern sky with 16.5 < R_59F_ <= 18.0.

This search complements the six previous SuperCOSMOS-RECONS (SCR) proper motion searches of the southern sky for stars within the same proper motion range, but with R_59F_<=16.5. As in previous papers, we present distance estimates for these systems and find that three systems are estimated to be within 25pc, including one, SCR 1546-5534, possibly within the RECONS 10pc horizon at 6.7pc, making it the second nearest discovery of the searches. We find 97 white dwarf candidates with distance estimates between 10 and 120pc, as well as 557 cool subdwarf candidates.
