Results are presented for 353 speckle interferometric observations of double stars, obtained in 2003 and 2004 at the USNO Flagstaff Station using the 1.55m Kaj Strand Astrometric Reflector. Separations range from 0.12" to 7.42", with a median of 0.42". These two observing runs concentrated on systems in need of improved orbital elements, and new solutions have been determined for 17 systems as a result.
