Abstract
The results of 3,989 intensified CCD observations of double stars, made with the 26-inch refractor of the U.S. Naval Observatory, are presented. Each observation of a system represents a combination of over two thousand short-exposure images. These observations are averaged into 1,911 mean relative positions and range in separation from 0.289 to 128.638, with a median separation of 8.669. Four orbits are improved. This is the 23rd in this series of papers and covers the period 4 January 2017 through 13 September 2017.
