Editor's Notes
- Like the Earth, the Sun has roughly the same pole-to-pole field, but below the surface, the magnetic field lines are tangled and irregular. Elections moving around in the Sun cause electric currents, just like the electrons that flow through wires.
- This is an image of the Sun taken by the Solar Dynamics Observatory. It is called a magnetogram. It is a map of magnetic activity on the Sun. The black and white areas indicate there is a high level of magnetic activity, and the gray areas indicate there is no magnetic activity. The white lines represent the complex magnetic field lines around the Sun.
- When magnetic field lines get twisted and tangeled together, they can build up a large amount of energy. This energy then can viontley unwind and cause an eruption. When these eruptions move away from the Sun into space, they are called solar storms.
- When solar storms head in Earth’s direction the high electric current effects technology here on Earth. The abundant amount of energy can cause problems with our technological, communication and navigation systems.
