 What is the role of sunspots in this phenomenon?
I suppose you might say my main job today is to find out all I can between activity on the Sun and various forms of activity on the Earth. Well, a sunspot is a form of solar activity. Just what is a sunspot? I'm afraid I can't say just what a sunspot is. A sunspot is a region on the Sun that is cooler than its surroundings. It means you can only approximately predict the future course of sunspot activity. Sunspots are mighty treacherous things. There is unquestionably a correlation between sunspots and disturbances of the Earth's magnetic field ... I think our biggest advance was the discovery that sunspots themselves are not the direct cause of the disturbances we have been studying on the Earth.
 Sunspots are what we are able to see, but serve only as an approximation of S-Regions, the true cause
 Sunspots are what we are able to see, but serve only as an approximation of S-Regions, the true cause  Sunspots were the key for Henry Middletown's breakthrough in the study  Sunspots were what inspired Dr. Niemand to do research on the Sun in the first place  Sunspots are the underlying cause of the issue, which are trackable by S-regions
