The results of 2014 speckle interferometric observations of doublestars, made with the 26 inch (66 cm) refractor of the US NavalObservatory, are presented. These observations are averaged into 1266mean positions and range in separation from 0.21" to 13.41", with a meanseparation of 2.61". This is the seventh in a series of paperspresenting measures obtained with this system and covers the period 2000January 10 through December 8.
