These are the 5 categories that measure geomagnetic storms
WEBOct 29, 2021 · Geomagnetic storms are expected to become more frequent in the next few years as the sun begins to move into the solar maximum phase of its 11-year cycle. NOAA has developed a 5-level scale, ranging from G1 to G5, to rate any incoming geomagnetic activity, giving a crucial way to quantify the expected impacts.

WEBGeomagnetic Storms. A geomagnetic storm is a major disturbance of Earth's magnetosphere that occurs when there is a very 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 ...

Geomagnetic storm - Wikipedia
WEBSizes are not to scale. A geomagnetic storm, also known as a magnetic storm, is a temporary disturbance of the Earth 's magnetosphere caused by a solar wind shock wave. The disturbance that drives the magnetic storm may be a solar coronal mass ejection (CME) or (much less severely) a co-rotating interaction region (CIR), a high-speed …
