Abstract

The W UMa-system U Pegasi was observed photoelectrically in two wavebands (B andV) in 1984. The light curves of this system are analysed using Kopal's frequency-domain technique and the optimisation method. New geometrical and physical elements have been determined and the period-variations discussed.
