The Carrington Event caused widespread terror in 1859! The geomagnetic storm caused the telegraph system to give electrical shocks to the operators, it set fire in offices and more. Apart from that, it generated auroras in areas on Earth that rarely, if ever, saw such a spectacle. The Carrington Event is considered the largest recorded account of a solar storm that hit Earth. But this is not the only geomagnetic storm in history that we have seen.
These days, the number of geomagnetic storms is rising and the reason is simple. A new solar cycle, which starts over every 11 years, has just begun. The Sun has begun its 'Solar Cycle 25', which is expected to peak in 2025. During this transition of the solar cycle, the Sun's surface transforms its nature from calm to stormy. And these solar outbursts shoot coronal mass ejections (CMEs), which are basically massive solar particles that generate geomagnetic storms on Earth and could cause power grid fluctuations, inconsistencies in satellite orientation, and radio blackout on Earth.
A massive solar storm is caused when a bubble of superheated gas, called the plasma or a coronal mass ejection (CME), is ejected from the surface of the Sun. A geomagnetic storm itself is a severe disturbance of Earth's magnetosphere that occurs when energy from the solar storm is transmitted very rapidly into the space environment around our planet. These CMEs carry the electrically charged particles which shoot towards the Earth and interact with the its magnetic field. This interaction causes all the electrical impact on Earth as well as the auroras at poles.
The effect of these geomagnetic storms can be measured. The National Oceanic and Atmospheric Administration uses the Geomagnetic Storms scale
