There is an excess of H and K emission in the faculae which surround sunspots, and epochs of
sunspot maximum coincide with epochs of maximum H and K.
Recent sunspot observations, which clearly show solar activity has been picking up, and that we are now en route to a
new sunspot maximum.
The GCR flux is highest at solar minimum so a narrow spike
at sunspot maximum has only a minor effect.
Solar physicists realized in the 1960s that the peak flare rate comes a few years after
the sunspot maximum.
Magnetic eruptions known as solar flares, which can disrupt power lines and interfere with aeroplane navigation, are more frequent during
the sunspot maximum.
In comparison:
the sunspot maxima where in 1957 (large), 1969 (small), 1980, 1989/1991 (double peak) and 2000/2002 (double peak).
Solar wind geometry through the sunspot cycles is currently running higher around
sunspot maxima and weaker between the sunspot maxima.
Certain chemicals from specific industries coupled with
a sunspot maximum or minimum should be correlated.
So it then predicts that the solar metric responsible, must be weaker around
the sunspot maxima and stronger between them during a cold AMO, and stronger around the sunspot maxima and generally weaker between them during a warm AMO.
