Figure 9: Distances from the measurement point to the position of the heavy part of the core in summer and winter This displacement of the core and the collapse of the gravitational force explains the occurrence of the surface tide at night. That's why it is directly opposite the daytime tide. All that has been said about the influence of the Sun also applies to the influence of the Moon. It is worth noting another fact - when summing up two sinusoidal signals, that is what will be from the influence of the masses of the Sun and Moon on the readings of the gravimeter, the trajectories are almost circular, a symmetrical signal shape is obtained. However, the measurement data (Figures 3-6) are clearly not symmetrical, which again confirms the influence of additional forces.
