Abstract:
    We present 2817 new southern proper motion systems with
    0.40"/yr>{mu}>=0.18"/yr and declination between -47{deg} and 00{deg}.
    This is a continuation of the SuperCOSMOS-RECONS (SCR) proper motion
    searches of the southern sky. We use the same photometric relations as
    previous searches to provide distance estimates based on the
    assumption that the objects are single main-sequence stars. We find 79
    new red dwarf systems predicted to be within 25pc, including a few new
    components of previously known systems.
