Eventually, the magnetic field dissipates, and the sunspot fades back into the brightness of the photosphere. These phenomena are not merely aesthetic curiosities; they are critical indicators of the Sun's complex magnetic activity.
Sunspots 101: Photosphere Dark Spots
They can persist for days or weeks, changing in size and shape as the magnetic configuration evolves. Feature Temperature (°C) Description Photosphere Average ~5,500 The Sun's visible surface, emitting white light.
When these magnetic field lines become twisted and concentrated, they rise through the convective zone and penetrate the photosphere. Moving outward, the layers include the radiative zone, the convective zone, and finally the atmosphere.

The atmosphere itself is divided into the photosphere, chromosphere, and corona. The Magnetic Origin of Sunspots Sunspots are the result of intense magnetic activity that originates deep within the Sun's convective zone.
