Correlation between the Sun's movement and sunspot cycles, courtesy Paul D. Jose. The pattern continues to match up to the present (2012). The 5 curves, from top to bottom are:

1) the distance from center of solar system mass to center of Sun,
2) the radius of curvature of Sun's path,
3) the rate of change in the angular momentum about the center of mass,
4) the rate of change in the angular momentum about the center of curvature, and
5) number of sunspots (up is one magnetic polarity and down is the other)
