  Orbits of 44 close and fast visual binaries are computed using the latest
speckle observations; 23 orbits are determined for the first time, the rest are
revisions, some quite substantial. Six combined orbits use radial velocities.
The median period is 15.6 years, the shortest period is one year. Most stars
are nearby late-type dwarfs. Dynamical parallaxes and estimates of the masses
are derived from the orbital elements and the photometry of the components.
