 What is the significance of the twenty-seven day cycle
This, be it understood, is fiction—nothing but fiction—and not, under any circumstances, to be considered as having any truth whatever to it. In the closing days of December, 1957, at the meeting of the American Association for the Advancement of Science in New York, Dr. Niemand delivered a paper entitled simply, "On the Nature of the Solar S-Regions." 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. What do you mean by activity on the Sun? NIEMAND. Well, a sunspot is a form of solar activity. I'm afraid I can't say just what a sunspot is. Isn't it true that the number of spots on the Sun rises and falls in a cycle of eleven years? The number of spots on the Sun rises and falls in a cycle of about eleven years. It means you can only approximately predict the future course of sunspot activity. 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. In the solar case it turned out to be these S-Regions. Philosophers have wrestled with it ever since the days of Job. Such a syndrome is characteristic of menopausal women and some men during the climacteric, but these people failed to fit into this picture.
