WEBSep 12, 2024 · During periods of low solar activity, the Sun can be devoid of any sunspots and thus be spotless. This is a frequent occurrence in the years around and during solar minimum. The graph below shows how many days during a specific year that the earth-facing side of the Sun had no sunspots.

Sunspots and the Solar Cycle | NESDIS
WEBThe 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.
