Abstract
THE possibility of a relationship between the periods of the sunspot cycle and the periods of the rotation of the planets has been investigated by several authors1–5. Such an interaction could be mediated by non-linear processes of gravitational wave conversion of the type which may, for example, be responsible for the acceleration of the equator of the Sun6,7. On the face of things, the most likely relationship should be that between the sunspot cycle and the period of rotation of Jupiter, gravitationally the dominant planet, but non-linear may imply that cross modulation products representing the combined effects of two or more planets may be the most easily recognizable.
