Abstract
New Photometric data in R and V passband filters of the classical Algol system U Cep were analyzed. The orbital and physical parameters of the system were obtained via light curve solutions, using Wilson-Devinney code. The absolute dimensions are also estimated. The O-C curve (only photometric data) is analyzed through Kalimeris method. Fourier analysis of P(E) function gave at least two modulation periods, i.e., P 1=16.38 yr and P 2=9.77 yr, the first was attributed to magnetic cycle effects and the second to mean time interval of occasional mass out bursts.
