The most significant G5 geomagnetic storm since 2003, recently hit the Earth and disrupted GPS, satellite navigation, and other technologies.
About Geomagnetic Storms
Geomagnetic storms, like the recent G5 storm, are disturbances in the Earth’s magnetosphere caused by solar wind activity.
These storms result from coronal mass ejections (CMEs) from the sun, which carry their own magnetic fields and can disrupt communications, power grids, and satellite operations on Earth and in near-Earth orbit.
On a scale from G1 to G5, G5 is the strongest level of geomagnetic storm (as per NOAA).
G1 - Minor
G2 - Moderate
G3 - Strong
G4 - Severe
G5 - Extreme
While a G4 storm can cause widespread power issues, a G5 storm could lead to complete blackouts and power grid collapses.
These storms can cause auroras in the sky and disrupt technologies like GPS and satellite navigation.
