Description:
    Accurate uvby light curves of the southern, detached, double-lined
    eclipsing binary V539 Ara (HR 6622A, HD 161783, V=5.71mag , B3V+B4V,
    P=3.17d) are presented. They contain 1409 observations in each colour,
    collected 1982-1984. Typical mean errors are 0.003-0.004mag.
    Observations for 8 additional times of minima from 1985-1994 are
    included. The secondary component belongs to the group of slowly
    pulsating B (or SPB) stars. An analysis of V539 Ara based on the new
    photometry and the spectroscopic orbit by Andersen (1983A&A...118..255A)
    is published separately (Clausen 1995).
