The barycenter data came from NASA’s Jet Propulsion Laboratory. I do not know how accurate it is. The data was created using 8 hour time segments. When selecting my dates I visually picked them off of graphs. Then I made graphs of the angular momentum 2 years on either side of the point. Added a regression line and distorted the graph so that the regression line came to a point and double checked my date.
The accuracy of the sunspot data is what it is.

I don’t know. About a year ago I came across an article “Solar Resonant Diffusion Waves as a Driver of Terrestrial Climate Change”. At the time I thought that this might also influence sunspot cycles. Unfortunately, astrophysics goes over my head very quickly and I didn’t know where to go for explanations. This website is a great resource of knowledge. I see all of these things as pieces of a puzzle that have to fit together. I believe everything I have presented so far fits. Now if I can just get a data set for Solar Resonant Diffusion Waves.

I did each one of the graphs with a different date range to show the ranges. Excel does not give an option of multiple dates—maybe I can do that.

Probably not. I’m just looking for correlations and patterns. My biggest hope for all of this work is that someone with the knowledge will see something significant and do a professional analysis.

I’m still trying to find a professional statistician to weigh in on this.
