Sunspot - Wikipedia
Solar cycles last typically about eleven years, varying from just under 10 to just over 12 years. Over the solar cycle, sunspot populations increase quickly and then decrease more slowly. The point of highest sunspot activity during a cycle is known as solar maximum, and the point of lowest activity as solar minimum.

Sunspots and the Solar Cycle | NESDIS
The solar cycle is a roughly 11-year periodic change in the Sun's sunspot activity, measured by the variation in the number of sunspots observed. Humans used telescopes to observe sunspots and solar cycles as early as the 17th Century; however, NOAA and NASA satellites are now major ways scientists use to study the Sun.
