Scientific paper

From 16 epochs of primary minima of SZ Psc the authors have determined an improved period of the system. The O-C residuals exhibit a sine wave modulation with a period of 45.2 years. Analysing the light curves of 1957 - 1984 for the distortion wave the authors have derived a period of twelve years with a semiamplitude of 0.04 of the light intensity of the system. In addition, a migration of the distortion wave, reported by other authors, has been followed and a period of 1.5 years has been derived.
