It's possible we may see more, as the sun is now at its peak of activity. In the mid-19th century, amateur astronomer Samuel Heinrich Schwabe realized that sunspots rise and fall in number in a cycle that repeats every 11 years. As sunspots increase, the sun grows more and more active. Enormous solar flares erupt from its surface, unleashing in seconds the energy of millions of nuclear bombs. If those flares are aimed toward the Earth, particles will interact with the Earth's magnetic field, producing auroral displays.
Sunspots are magnetic in nature and so come in pairs, like the ends of a magnet.
Because sunspots are cooler than the surrounding parts of the sun, they appear as irregular, dark splotches across the solar face. Many are larger than the Earth and can be seen by the naked eye. To view sunspots safely, use only the filters specifically made for solar observing. Mirrored sunglasses won't protect your eyes no matter how many pairs you use. Neither will layers of negatives or smoked glass.
