Remark: A well-documented light-time effect (P = 294.3d, the semi-amplitude of the O-C residuals is 0.0059d) because of a third body on an eccentric orbit. Precession causes changes of the brightness amplitude: the amplitude of the MinI was observed to vary between 0.46m and 0.70m and that of MinII, between 0.37m and 0.55m. The depths of minima reached their maximum values about JD 2445800 and began to decrease [N0176].
