The Yale-San Juan speckle interferometry program, a collaboration primarily between Yale Southern Observatory and the Universidad Nacional de San Juan (Argentina) was active between 1994 and 1996, using two telescopes at the El Leoncito, Argentina, site. Over the two and a half year period, more than 2000 observations of binary stars were made. The purpose of these observations was to obtain fundamental position angle and separation measurements for a large number of Southern Hemisphere visual and speckle binaries. From such measures mass information may ultimately be derived. Some measures, including all those taken at the Complejo Astronomico El Leoncito 2.15-m Telescope have already appeared in the literature (e.g. Horch et al. 2001, AJ, 121, 1597), but most of the observations were taken at the 76-cm telescope at the Carlos U. Cesco Observatory. We present the status of the analysis of these data, information regarding measurement precision at the 76-cm telescope, observational statistics such as number of stars analyzed and a histogram of the seeing measures, and some sample results. We gratefully acknowledge NSF support of the Yale Southern Observatory and support from the Chester F. Carlson Center for Imaging Science at RIT.
