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
to
. We have used there new speckle measurements to improve the
orbital elements for the binaries COU 247 and BU 524 AB.
Key words: binaries: visual / interferometry
