Description	We analyzed a new photometry of this well-known Algol-like eclipsing binary together with old photoelectric measurements with the aim of better understanding of its orbital period changes and short-time light variations modulating the mean light curve. The analysis has been done by the new method based on the principal component analysis and robust regression. New spectroscopic observations and radial velocity curve are also presented, as well as the solution of the light curve of the system.
