Abstract: Results are presented for angular separation, position angle and V and R photometry for 2373 binary stars, obtained with the CCD camera on the 1-m Jacobus Kapteyn Telescope at La Palma. The stars are part of the Input Catalogue of the Hipparcos Astrometric Satellite launched in 1989 August, and the purpose of our measurements is to assist in the satellite reductions. The A-components of the binaries have V magnitudes in the range 8 to 12 mag, and A-B angular separations (rho) 0.5-30 arcsec with the majority in the range 0.5-5 arcsec. The internal consistency achieved for the photometry is less than 0.01 mag for components of nearly equal brightness, deteriorating to 0.1 mag for Delta(v) of about 4 mag. For the astrometry, the internal consistency for rho varies between 0.01 and 0.1 arcsec, being worse for small separation and large Delta(v).
