Sunspot - Wikipedia
WEBSunspot number is correlated with the intensity of solar radiation over the period since 1979, when satellite measurements became available. The variation caused by the sunspot cycle to solar output is on the order of 0.1% of the solar constant (a peak-to-trough range of 1.3 W·m −2 compared with 1366 W·m −2 for the average solar constant).

Sunspots - NASA Science
WEBSunspot Groups Are Often Associated with Active Regions. Active regions are areas on the Sun where strong magnetic field lines extend into the solar atmosphere. Because of this, scientists often find sunspots in the same area as active regions. Solar eruptions, like solar flares and coronal mass ejections, typically burst from these active regions.

WEBSep 13, 2024 · Sunspots are areas that appear dark on the surface of the Sun. They appear dark because they are cooler than other parts of the Sun’s surface. Solar flares are a sudden explosion of energy caused by tangling, crossing or reorganizing of magnetic field lines near sunspots. The surface of the Sun is a very busy place.
