Scientific paper

Between December 23-29, 1981, photoelectric observations of ZZ Aur were made at the Yunnan Observatory, and 603 measurements in yellow light and 604 measurements in blue light were obtained. The epochs of two principal minima and two secondary minima are secured, and it is found that the period of ZZ Aur was just beginning to change. The main component to have spectral type A5V, and the secondary component, GOV; and it is proposed that this system may be a main-sequence binary at the limit of stability.
