How long do sunspots last?

Answer

The duration of sunspots varies greatly as some of them only last hours, while others can last for many months. The longest-lasting known sunspot, which lasted 6 months, was recorded in 1943. Sunspots have an enormous variation in size as well.

Sunspots are visible as dark patches on the sun's surface, as they are areas with lower temperature, around 4000 C, and the surface temperature of the sun is around 6000 C. The amount of visible sunspots follows a 11-year cycle. In modern times, the cyclic period of sunspots has been consistent. However, hardly any sunspots were seen from about 1645 to 1715.
