SPECKLE INTERFEROMETRY AT THE US NAVAL OBSERVATORY .1.

We present speckle interferometer measurements of 467 binary stars tak en at the US Naval Observatory in Washington, DC, using the 66 cm refr actor, from 1990 October through 1992 December. The observing program is designed to provide high-quality observations of binaries in the 0. '' 3-3.'' 5 range of separations and as faint as 10.0 mag. More than 8 000 measurements have been made to date, of which we report the result s for 2329. Not only is it our intent to provide accurate data for int eresting binary stars, but also, by careful calibration, to firmly rel ate the ''classical'' astrometry of binary stars to that being obtaine d today by speckle and that which will soon be obtained by other moder n techniques such as long-baseline optical interferometry.
