Abstract: The possibility that the orbital period variation is connected with the light curve changes has been investigated for the contact binary solar--like system TZ Boo. The O'Connell effect and the minimum depth variation have been studied. The results may be through a light on the magnetic activity of the system. The system possesses the O'Connell effect with a cycle of 4.6 years while the depths variation has an 8.1 year cycle. The (O-C) residual variations may be caused by a magnetic activity cycle mechanism, but it remains speculative.
