Paper I showed that the epochs when the lunar line-of-apse points directly towards/away from the Sun, at times that were closely aligned with the Equinoxes and Solstices (i.e. seasonal boundaries), exhibited distinct periodicities at 28.75, 31.00, 88.50 (Gleissberg cycle), 148.25, and 208.00 (de Vries cycle) years. The caveat being that the alignments had to observed in a frame of reference that was fixed with respect to the Perihelion of the Earth’s orbit. This study expands upon the findings of paper I by showing that the long-term periodicities exhibited by the alignments of the lunar line-of apse with the seasonal boundaries have effectively the same periodicities as the alignments of the Perigean New/Full moons with the seasonal boundaries (provided both are viewed in a frame of reference that was fixed with respect to the Perihelion of the Earth’s orbit). In addition, this study establishes that the very process of selecting the times when the Perigean New/Full moons occur at or near seasonal boundaries, is in fact equivalent to selecting the times when the strongest Perigean New/Full moon tidal events cross the Earth’s equator or when they are at their furthest distance from the Earth’s equator (i.e. lunar standstill).
