There's a little black spot on the sun today
It's the same old thing as yesterday
There's a black hat caught in a high tree top
There's a flag-pole rag and the wind won't stop
A sunspot is a region on the Sun's surface (photosphere) that is marked by intense magnetic activity, which inhibits convection, forming areas of reduced surface temperature. They can be visible from Earth without the aid of a telescope. Although, they are at temperatures of roughly 4,000–4,500 K, the contrast with the surrounding material at about 5,800 K leaves them clearly visible as dark spots, as the intensity of a heated black body (closely approximated by the photosphere) is a function of T (temperature) to the fourth power. If a sunspot were isolated from the surrounding photosphere it would be brighter than an electric arc.

Isn't that the whole that is releasing all of the energy causing our magnetic field to act up?
