Speckle Interferometry at Mount Wilson Observatory: Observations Obtained in 2006-2007 and 35 New Orbits
Results are presented for 607 speckle interferometric observations ofdouble stars, as well as 222 measures of single stars or unresolvedpairs. All data were obtained in 2006 and 2007 at the Mount WilsonObservatory, using the 2.5 m Hooker telescope. Separations range from0farcs06 to 6farcs31, with a median of 0farcs34. These three observingruns concentrated on binaries in need of confirmation (mainly Hipparcosand Tycho pairs), as well as systems in need of improved orbitalelements. New orbital solutions have been determined for 35 systems as aresult.
