What Are Sunspots and Why Do They Form? At their core, sunspots are intense magnetic storms on the Sun's photosphere. The twisted magnetic fields that define sunspots are the launchpads for solar flares and coronal mass ejections (CMEs).
Sunspot Activity vs Solar Irradiance: Understanding the Impact on Earth
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.
When these events are directed toward Earth, they interact with our planet's magnetosphere, triggering geomagnetic storms. These storms can cause a range of effects, from the beautiful auroras seen at high latitudes to radio blackouts, satellite drag, and even induced currents in power grids that threaten electrical infrastructure.
