Title: Speckle interferometry of ``fast'' binaries

Abstract: Relative positions and magnitude differences of 375 close binaries with fast orbital motion (periods less than 30 yr) will be measured to determine or improve their orbital elements. This will contribute to the statistics of orbital elements and masses, enable dynamical studies of systems that present particular interest, and disentangle orbital motion from the astrometric parameters (parallax and proper motion).
