Robert M Wilson: On The Distribution of Sunspot Cycle Periods
Back in 1987, Robert M Wilson of NASA’s Space Science Laboratory in Huntsville published this paper in the Journal of Geophysical Research. It’s important to our solar-planetary theory because it shows that the Sun is bi-modal in terms of its solar cycle lengths. They cluster around periods of a little over ten and a little under twelve years. These periods correlate to the periods of Jupiter-Earth-Venus syzygy cycles and Jupiter’s orbital period respectively. Leif Svalgaard vehemently denied this correlation when I pointed it out to him a few years ago.
The same correlation was noted by independent researcher Timo Niroma in 1989, who conducted his own survey and analysis of solar cycle lengths. He produced this simple ascii-art graphic to present his results.
Ray Tomes and later, our own fellow researcher Ian Wilson determined the exact length of the J-E-V syzygy cycle to be 10.39 years. Jupiter’s orbital period is 11.86 years.
Also in 1989, french independent researcher Jean-Pierre Desmoulins created a simple program in Turbo-Pascal to calculate the ‘most aligned days’ for J-E-V (green curve) and compared the results graphically with the signed sunspot series (red curve), producing this graphic.
Venus Earth Jupiter alignments vs The solar cycles
The out of phase epochs on this plot in the late 1700’s and late 1900’s presage the Dalton minimum and the current Landscheidt minimum getting under way with the anomalously low solar cycle 24. However, Desmoulin’s planetary index, whilst accurately predicting the epochs of solar minimum in most cycles, cannot predict their amplitude. That’s something we’ve been working on here at the Talkshop, and I’ll outline our progress in another post soon.
