Ser. 134 545 1999 1999A&AS..134..545A V/39 : 4th Catalog of Orbits of Visual Binaries (Worley+, 1983) Binaries, orbits Stars, double and multiple binaries: close techniques: interferometric We present speckle observations of 48 double and multiple stars observed with the 2-meter ``Telescope Bernard Lyot'' (TBL) in December 1995, January 1997 and June 1997. Angular separations, absolute position angles and relative photometry result from these observations. New orbital elements have been recalculated for 8 double stars.
