A local cosmological near-constant number imbedded in the structure of the solar system forms a 178.867624:1 ratio between the main rhythm of the solar system centre of mass and the year on earth. Centre of Mass against Position of the Sun (COMPOS) charts 600 years of solar system centre of mass data. The number 178.867624 is derived by plotting all main turning points of this chart and averaging their period. This constant describes a main structure of time, a periodic cycle of the solar system resulting from the interaction of Sun, Jupiter, Saturn and Neptune. Uranus, as the fourth big planet, is slightly out of alignment with this basic underlying cycle, and produces the secondary wiggle moving backwards against the 179 year JSN permanent cycle. Jupiter, Saturn and Neptune also slowly drift away from exact harmonic relations, but the main SSB 178.9 year cycle continues against these longer wave patterns.
Of interest for sunspot prediction dates, Jupiter-Saturn SSB Sunspot cycle posted by JimP at Jupiter influencing sunspots shows that a specific pattern of sunspots were aligned directly with the Jupiter-Saturn cycle in ~1893-1913 (my ‘cycle 3’) and also in the corresponding period 179 years before at ~1710-1730 (my ‘cycle 2’). I believe this pattern is of interest, as my COMPOS chart clearly shows the planets produced this same pattern at SSB cycles 1 (~1535-55) and 4 ( ~2070-90). Cycles 2 and 3 are those for which historical sunspot data exist.
As well, 178.867624 is 1/144th of the earth’s precessional period of ~25764 years. Ray Tomes has noted that harmonic cycles of period 2 and 3 are common in nature, making combined cycles of period 12 also common. The combined period of 3x4=12 SSB cycles closely matches 1/12 of the precession. This is an example of harmonic resonance in the solar system, entraining the precession period against the solar system barycentre.
My chart showing 178.867624 as a near-constant was first posted in response to Ray Tomes’ thread Explaining Planetary Alignments Relationship to the Sunspot Cycle . As Ray notes it presents a separate ATM idea.
