Abstract:
The results of 2014 speckle interferometric observations of double
stars, made with the 26 inch (66cm) refractor of the US Naval
Observatory, are presented. These observations are averaged into 1266
mean positions and range in separation from 0.21" to 13.41", with a
mean separation of 2.61". his is the seventh in a series of papers
presenting measures obtained with this system and covers the period
2000 January 10 through December 8.

Note (1): A number indicates the number of years since the system was last
measured and only given for systems with ≳50years.
C = Confirming observation;
x = large separation change since Hipparcos measure;
y = large change in position since last measure;
z = disagrees with Hipparcos measure, but matches the reprocessing of
Fabricius & Makarov (2000, Cat. J/A+AS/144/45) quite well.
