Abstract:
The results of 3362 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
1970 mean relative positions and range in separation from 0.78" to
72.17", with a mean separation of 14.76". This is the 17th in
this series of papers and covers the period 2010 January 6 through
December 20. Also presented are 10 pairs that are resolved for the
first time.

History:
* 25-Sep-2012: From electronic version of the journal
* 07-Dec-2012: In order to agree with the WDS, changed components
like "A-BC" into "A,BC". These changes concern the binaries
