Abstract:
The results of 1068 speckle interferometric observations of double
stars, made with the 26 inch (0.66 m) refractor of the US Naval
Observatory, are presented. These observations are averaged into 841
means of 815 binary stars. The systems range in separation from 0.22"
to 6.01" with a mean separation of 2.21" and have a limiting secondary
magnitude of V=12.5. This is the sixth in a series of papers
presenting measures obtained with this system, and it covers the
period 1999 January 1 through 2000 January 9.
