Who is more likely to be affected by the impact of a CME with the Earth ?
A coronal mass ejection can affect various systems in different ways. In extreme cases, electrical currents can be induced in long metal structures, like power lines and oil/gas pipelines. Additionally, the high-speed charged particles of the CME can cause the buildup of electrical charge in metal structures in satellites; such buildups of electrical charge can be damaging to the sensitive electronic systems common in telecommunications satellites. Because of the possibility of damage to these vital and very expensive systems, advance knowledge of the likelihood of a CME is potentially helpful to the operators of such systems. However, not all the effects of CMEs are bad. The beautiful aurora borealis and aurora australis (Northern and Southern Lights) are caused by the influence of CMEs with the magnetic field surrounding the Earth. Roughly speaking, this interaction with the Earth’s magnetosphere forms a kind of magnetohydrodynamic dynamo — like an electrical generator — which can
