We have successfully observed three binaries, ∑346AB, Kui23 and ∑73 by speckle interferometry, which overcomes atmospheric effects and resolves binary separations close to the limiting resolution of the telescope. The speckle interferograms were obtained on 1986 December 23 and 24, recorded with Yunnan Observatory No.1 CCD Receiver attached to our 1-metre telescope. The measured separations are 0.28`` +/- 0.01'' (∑346AB), 0.24`` +/- 0.01'' (Kui 23), and 0.70`` +/- 0.01'' (∑73).
