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].
