This shearing motion stretches and twists the star's magnetic field lines, creating regions of intense magnetic flux that rise to the surface. When these magnetic fields emerge, they inhibit the convective flow of hot plasma from the Sun's interior, effectively "cooling" the surface in that specific area and creating the observed spot.

These temporary features dictate space weather, influence the heliosphere, and can directly affect technology and infrastructure on Earth and throughout the solar system. The twisted magnetic fields that define sunspots are the launchpads for solar flares and coronal mass ejections (CMEs).
Scientists use the International Sunspot Number (ISN), a value calculated from observations of the number of groups and individual spots, to track the progression of the cycle and compare current activity to historical patterns. When these events are directed toward Earth, they interact with our planet's magnetosphere, triggering geomagnetic storms.
Sunspot Activity Cycle Maximum Insights
What Are Sunspots and Why Do They Form? At their core, sunspots are intense magnetic storms on the Sun's photosphere. As the cycle progresses toward solar maximum, the number of sunspots increases dramatically, and new ones can form daily.
