Speckle interferometry at the USNO flagstaff station: Observations obtained in 2003-2004 and 17 new orbits

Results are presented for 353 speckle interferometric observations of double stars, obtained in 2003 and 2004 at the USNO Flagstaff Station using the 1.55 m 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.
