Abstract
The UBV observations of a marginal contact system BX And obtained duri ng 1987, 1989 and 1990 seasons at the Ankara University Observatory ar e presented. Based on all available light curves of the system we stud ied light curve variations, particularly at the extrema points. Time s cale of the variations was found as short as a few cycles of the orbit al revolution. Six new estimates of the minima times are given. Some i ndications are found that the system might be detached or semi-detache d.
