Scientific paper

Results of 42 angular-separation and position-angle measurements for 28 binaries are presented obtained with speckle interferometric technique at the BTA 6-meter telescope. The system ADS 11311 (φ Dra) earlier has not been measured with speckle interferometric technique. The system ADS 11149 has been identified as being triple for the first time in speckle interferometric measurements. The procedure of recording initial images and their further processing is presented. Comparison of the results presented in this work with ephemerides and results of other observers indicates the absence of serious systematic errors.
