Position angle and separation measures of 482 primarily southern binary stars are presented. These were obtained from speckle observations taken at the Carlos U. Cesco Observatory, El Leoncito, Argentina, using a multianode microchannel array detector during the period 1994 July to 1996 July. When comparing our measures to the ephemeris predictions in the case of objects with well-determined orbits, we find that our measures have a precision of approximately 13 mas per observation in separation and 075/ρ in position angle, where ρ is the separation in arcseconds. We briefly discuss the photometric properties of the data and highlight four southern binaries of particular interest that emerge from the list presented.
