| Abstract: | Photoelectric observations in B and V for the FZ Del system are presented and its light curves are analyzed. Absolute parameters
are obtained. The system shows a near contact subgaint secondary component with a likely K1 spectral type. The O-C curve is
presented and probably a secular orbital period variations is detected on a timescale of about 6.9×106 yrs, suggesting thermal timescale mass transfer. A new light elements for the system have been obtained. The system can be
considered as an early stage of conservative case of mass transfer.
