摘要：

We present the first results of our speckle interferometric measurements of binary stars made with the ICCD speckle camera using the 1.52-m telescope of the Observatorio Astronomico Nacional at Calar Alto (Spain) in September, 1999. The data contain 123 observations of 83 systems. The measured angular separations range from 0." 153 to 6." 727. We have used there new speckle measurements to improve the orbital elements for the binaries COU 247 and BU 524 AB.
