Speckle Interferometry at the USNO Flagstaff Station: Observations Obtained in 2003-2004 and 17 New Orbits

Abstract

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.
