Measurements of visual double stars made at PIC DU Midi and at Nice Fifty visual measures of 37 very close binaries observed with the 2-mtelescope at Pic du Midi are presented together with 601 measures of 245close binaries observed with the 74-cm and 50-cm refractors at Nice. Allmeasurements were made by micrometer with illuminated wires. With the2-m telescope, binaries as close as 0.07 arcsec are separated, usingmagnifying powers from 2500 to 5000.

Measurements of double stars at Nice with 74-cm and 50-cm refractors A total of 717 measures of 287 binaries made at the 74-cm and 50-cmrefractors are presented. These are mostly very close binariesdiscovered recently, for which a rapid orbital motion is evident forabout 30 percent.

Micrometer measurements of visual binaries A total of 376 micrometer measurements of 116 visual binaries made atthe Nice Observatory, France, in the years 1980-1983 is presented. Eachpair is identified by the A.D.S. number, the name of the couple, and theB.D. number. The next line gives the I.D.S. number, the A.D.S.magnitudes, and the spectral types. This is followed by the epoch of theobservation, the observed position angle and distance of the components,and the aperture of the refractor used. The means and the residuals fromknown orbits are given in the next lines. The symbol 'N' denotes thatthe observations were made with a 74-cm refractor; the symbol 'n'denotes a 50-cm refractor.
