Abstract
Abstract The results of 4747 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 2000 short-exposure images. These observations are averaged into 2667 mean relative positions and range in separation from 0.″328 to 95.″9, with a median separation of 8.″673. Eight orbits are improved. This is the 22nd in this series of papers and covers the period 2016 January 4 through 2016 December 29.
