Caption: Sunspot observations, made in September 1859 by J. H. Griesbach. The sunspots are the dark areas on the Sun. The exact dates and times are noted next to each drawing. Sunspots, first observed with telescopes in 1610, are areas of magnetic activity that are cooler than the rest of the Sun's surface. As telescope designs improved, more detailed studies were made, allowing sunspots to be used to track solar activity.
