geomagnetic storm, also called magnetic storm or solar 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.

A magnetic storm is a period of rapid magnetic field variation. It can last from hours to days. Magnetic storms have two basic causes: The Sun sometimes emits a strong surge of solar wind called a coronal mass ejection. This gust of solar wind disturbs the outer part of the Earth's magnetic field, which undergoes a complex oscillation.

2003/10/29 · Top 50 geomagnetic storms On this page you will find an overview of the strongest geomagnetic storms since January 1994 together with links to more information in our archive. The Kp-values on this page are the official, finalized Kp-values from the GFZ in Potsdam, Germany. The Ap-index provides a daily geomagnetic activity average.

2022/6/29 · Researchers are studying past storms, including the most intense storm of the space age – the March 1989 geomagnetic storm – to determine future risk. The 1989 storm caused a nine-hour...

2022/4/7 · A geomagnetic storm is a major disturbance of Earth's magnetosphere that occurs when there is an efficient exchange of energy from the solar wind into the space environment surrounding Earth. These storms result from variations in the solar wind that produces major changes in the currents, plasmas, and fields in Earth’s magnetosphere.
