Abstract:

The results of 3056 speckle interferometric observations of double stars made with the 26 inch 66 cm refractor of the US Naval Observatory are presented. Each speckle interferometric observation of a system represents a combination of over a thousand short-exposure images. These observations are averaged into 1675 mean relative positions and range in separation from 0.19 to 45.21 with a median separation of 2.99. This is the ninth in a series of papers presenting measures obtained with this system and covers the period 1 January 2002 through 29 December 2002. Included in these data are 28 older measures whose positions were previously deemed possibly aberrant but are no longer classified this way following a confirming observation. Nine of these systems have new orbital elements which are presented here as well.
