This paper is a continuation of diffraction-limited speckle interferometry of binary and multiple stars
carried out at the 6-m telescope of the Special Astrophysical Observatory in Zelenchuk.
The program has concentrated on nearby ( mas) close binaries discovered or measured
during the Hipparcos mission.
Here, we present 132 measurements of relative positions and magnitude differences for
99 pairs and 8 measurements for 6 triple systems.
54 entries in the paper are new Hipparcos binaries.
New triple systems with late-type dwarf components, discovered in the course of observations, are
HIP 8533 and HIP 25354.
Key words: stars: binaries (including multiple): close / techniques: interferometric
