Another effect of the interaction between the Solar Wind and the Earth’s magnetic field seems to be that it affects the Earth’s rate of rotation where Solar Minima lead to accelerations and Solar Maxima to decelerations (as discussed in previous papers; [2,5-10]). Several authors have noted a correlation between sunspot activity and Earth’s rotation [2,8-23] or Solar-planetary cycles and Earth’s rotation [10,24-32].
Golovkov  plotted Earth’s rate of rotation (spin rate) against sunspot numbers and found that high spin rates correlated with low sunspot numbers and low spin rates with high sunspot numbers. Mörner  plotted LOD against sunspot numbers for the period 1831–1995 and found a linear relationship where low LOD values (high spin rate) correlated with low sunspot numbers and high LOD values with high sunspot numbers. Consequently, the Earth’s rotation accelerates at low solar activity and decelerates at high solar activity.
The relations among solar activity, Solar Wind, variations in Earth’s atmospheric shielding capacity and variations in the Earth’s rate of rotation are expressed in Fig. 1
