Abstract
We present speckle interferometer measurements of 467 binary stars taken at the US Naval Observatory in Washington, DC, using the 66 cm refractor, from 1990 October through 1992 December. The observing program is designed to provide high-quality observations of binaries in the 03-35 range of separations and as faint as 10.0 mag. More than 8000 measurements have been made to date, of which we report the results for 2329. Not only is it our intent to provide accurate data for interesting binary stars, but also, by careful calibration, to firmly relate the "classical" astrometry of binary stars to that being obtained today by speckle and that which will soon be obtained by other modern techniques such as long-baseline optical interferometry.Keywords
