Penumbra
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.
A cooler area on the sun is called a sunspot
The darkest part, where the magnetic field is approximately vertical to the sun's surface is called the Umbra.
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.
A cool, dark area on the sun's surface is called a sunspot. Sunspots are areas of reduced temperature that appear dark against the brighter background of the surrounding solar surface because they are regions of concentrated magnetic field flux inhibiting convective flow.

An area on the sun that is cooler is called a sunspot.

No. A sunspot is a slightly cooler area of the surface associated with magnetic disturbances within the Sun. The eruptions of gas are called prominences, and they are related to the phenomenon called solar flares.
The center portion of a sunspot is called the umbra. It is the darkest part of the sunspot where the magnetic field is strongest and the temperature is cooler than the surrounding areas.
