1 Introduction

The interest in visual binary systems has been boosted with the advent of the Hipparcos mission. They form of course an important element in our knowledge of the constitution of the Universe and our understanding of the evolutionary behaviour of stars near and away from the Main Sequence. Nevertheless, data on visual double stars are still largely incomplete and wanting; especially astrophysical information is fragmentary and often surprisingly poor in quality and quantity.

In the frame of an attempt to close this lack of observations, Nakos et al. (1997) (Paper I) have recently presented V magnitudes, (B -V) and (U-B) colours of close visual double star components, and their differences as well as separations and position angles of 42 such visual double stars.
The sample of paper I and the present paper was selected for angular separations from 2.5'' to about 5'', and magnitude difference under 1.25. The magnitudes of the components given in the WDS (Worley & Douglas 1984) are between 8 and 10 and the spectral type of the primaries as G.
We present now UBV magnitude and colour differences of additional 42 such visual double stars.
