Here’s a prediction graph I produced a little while ago which seems to be more or less on course:
It uses the fact that changes in Earth’s length of day seem to precede changes in solar magnetism and sunspot production by several years. The yellow curve was generated by combining Sunspot data with LOD data to create a prediction for Ap out to 2015. The recent burst of sunspot activity has arrived on cue.
Here’s another graph which shows a possible correlation between sunspot activity averaged over the length of the solar cycle, and motion of the solar system’s centre of mass relative to the solar equatorial plane averaged over two Jupiter orbital periods:
What caused the collapse in solar activity at the start of the 1800′s known as the Dalton minimum? Could it be the conjunction of Uranus and Neptune which seems to accompany each of the grand minima? Does that mean we are due another one now? I’ll investigate that in another post soon.
Why does the average sunspot number fall when the average mass of the planets is heading south? Speculatively, could it be that the ‘lensing’ of an electro-magnetic effect emanating from the galactic centre diminishes when the planets are ‘on the wrong side of the sun’?
