 In observing the sunspot-related disturbances, what pattern did Niemand notice? What pattern did Niemand notice of the disturbances? (daytime, strangers)
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. 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. 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.
