Prominence Sunspot in 1945

Sunspot maximum and sunspot minimum are the points in time (roughly 6 years apart) when the sun is producing the most, or the least sunspots. In the past this has been measured both by sunspot area and sunspot count and is directly tied to the solar magnetic cycle.

This question makes no sense. It's like asking "what is an example of a pencil?" A pencil is a pencil, and a sunspot is a sunspot.

The sunspot cycle is about 11 years in length.

A Large Sunspot can be up to about 10,000 miles across.
