In what year did the last sunspot occur?

Sunspots are a natural phenomenon that occur in cycles, with periods of maximum and minimum solar activity. As of my last update in October 2023, sunspots continue to appear as part of the solar cycle. The most recent solar cycle, Solar Cycle 25, began in December 2019, and sunspots have been observed within this cycle. Therefore, there is no definitive "last sunspot" year, as they are ongoing.
