Speckle Interferometry at the U.S. Naval Observatory. XIV

Abstract

The results of 2033 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 1297 mean relative positions and range in separation from 0. 54 to 58. 96, with a mean separation of 14. 99. This is the 14th in this series of papers and covers the period 2007 January 17 through 2007 December 31. The first two resolutions of closer companions to previously known wider pairs are also presented.
