Walraven photometry of nearby southern OB associations
Homogeneous Walraven (VBLUW) photometry is presented for 5260 stars inthe regions of five nearby southern OB associations: Scorpio Centaurus(Sco OB2), Orion OB1, Canis Major OB1, Monoceros OB1, and Scutum OB2.Derived V and (B - V) in the Johnson system are included.

| Four-colour photometry of hydrogen-deficient stars and related objects
Stromgren uvby photometry of hydrogen deficient and helium-weak starssuggests that the 'extreme helium' (= 'hydrogen deficient') stars whichhave been well observed are all variable, probably in a complex way.Previously observed short-term variability of HD 160641 and long-termvariability of HD 168476 are confirmed. There is no evidence forvariability in the intermediate helium stars or the helium-weak stars.
