Scientific paper

Binary-star measurements by speckle interferometry are reported. The measurements were performed with a 1-m telescope and with a 1.8-m telescope. The faintest resolved binary star was ADS 2630 (8.9/9.3 mag; probably the faintest binary star measured by speckle interferometry). The autocorrelation of this binary star was reconstructed from only 40 speckle interferograms. The spectroscopic binary Alpha Aur (separation about 0.06 arcsec) was resolved with the 1.8-m telescope. Four of the measured binary stars were Hyades binaries.
