Sorry David109, I have been away for a few days and so my reply is delayed somewhat.
This is figure 6 from our 2008 paper:
Wilson, I.R.G., Carter, B.D., and Waite, I.A., 2008, Does a Spin-Orbit Coupling Between the Sun and the Jovian Planets Govern the Solar Cycle?, Publications of the Astronomical Society of Australia, 2008, 25, 85 – 93.

If you extend the plot forward in time, you get a negative number of years that the syzygies of Jupiter and Saturn are ahead of the time of solar maximum for solar cycle 24:
Jupiter-Saturn Syzygy around February 2011 Sunspot maximum April 2014 Difference in years -3.2 years
Which indicated that solar cycle 24 would be weak.
However, there has been considerable additional work done on this topic since 2008.
Why has the graph not been update to 2017?
ReplyDeleteAn interesting theory.
