Jupiter - the Jovian cycle 11,86 years

Jupiter is by far the most important influencer on the sunspot cycle.

Late Timo Niroma did a lot of work on this.

I start with the list of sunspot cycles.

At each sunspot minimum I have retrieved the planetary positions. For quick lookups I often use Asynx Planetarium, but here I used an excel spreadsheet that I got from a french colleague a long time ago. I will find his name and credit him in a comment, and also upload the spreadsheet so you can use it.

So the first thing to look at is the Jupiter (heliocentric) position at solar minimum.

The minima are clustered in three intervals, marked with A, C and B.

I chose this order/colors a long time ago and have sticked with it.

This is what the list looks like (color identifies what interval the minima belongs to).
It showns how the minima go from C to A to B to C.... and so on (with an exception in SC5).
