Geomagnetic storm | Solar Wind, Auroras & Magnetosphere
Oct 16, 2024 · Geomagnetic storm, disturbance of Earth’s upper atmosphere brought on by coronal mass ejections—i.e., large eruptions from the Sun’s outer atmosphere, or corona. The material associated with these eruptions consists primarily of protons and electrons with an energy of a few thousand electron volts.
