Abstract:

Observations of OB-stars, made in 1959 and 1960 at the Leiden Southern Station near Hartebeespoortdam, South Africa, with the VBLUW photometer attached to the 90 cm light-collector, are given in this paper. They are compared with photometry obtained by Graham (1968), Walraven & Walraven (1977), Lub & Pel (1977) and Van Genderen et al. (1984). Formulae for the transformation of the present observations to those of Walraven & Walraven (1977) and Lub & Pel (1977) are given.

Key words: stars, early type -- stars, fundamental parameters (colours)
