Group moving stars in the South Polar Cap were identified from their common proper motions. Twenty-six pairs and groups have been selected whose average annnual total motions generally exceed O”.140. Similar works in other Yale Zones were reported early are now under spectroscopic .and photometric investigations.With the available of parallaxes of few stars and estimated distance from spectra, the transverse motions is obtained to about 100 km/set. Radial velocity is under the current study. Photometric and kinematic properties of moving groups are important to the understanding of galactic structure.
