Present O–C diagram for the eclipse times of N782. The sinusoidal curve represents the LITE with the short period of about ten years and a very small semi-amplitude of 4.3 sec. The individual primary minima are denoted by circles, the secondary by triangles. The first group of mid-eclipse times close to the cycle −15 000 derived by Lohr et al. (2014) from the SuperWASP database was not taken in consideration due to the large scatter of these data.
