A sun spot
The darkened area of a sunspot is called the umbra. It is the central region of a sunspot where the magnetic field is strongest, causing the area to appear darker compared to the surrounding photosphere of the Sun.

The darkened area of a sunspot is a region of cooler temperatures on the Sun's surface, known as the umbra. Sunspots are caused by intense magnetic activity that inhibits convection, leading to lower temperatures in these areas compared to the surrounding photosphere.
An area on the sun that is cooler is called a sunspot.
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.
