A severe G4 geomagnetic storm hit Earth on Sunday, according to a National Oceanic and Atmospheric Administration (NOAA) alert. In its message, the agency added that a major disturbance in the planet’s magnetic field ‘often varying intensity between lower levels and severe storm conditions over the course of the event’ are expected.

The NOAA further added that people should not panic. They ‘should not anticipate adverse impacts and no action is necessary, but they should stay properly informed of storm progression by visiting our webpage’. The G4 geomagnetic storm can also have technology effects.
“Infrastructure operators have been notified to take action to mitigate any possible impacts. Possible increased and more frequent voltage control problems – normally mitigable. Increased possibility of anomalies or effects to satellite operations. More frequent and longer periods of GPS degradation possible,” the NOAA alert on Sunday stated.
A space weather handle on X, platform formerly known as Twitter, said that the severe G4 geomagnetic storm (Kp8) hit Earth with the threshold reached at 16:28 UTC. Another one added that the the storm is fast-moving and hit more than 12 hours earlier than anticipated.
Geomagnetic storms have the potential to produce a display of the aurora borealis over the North Hemisphere. NOAA had earlier said that satellites detected at least one flare and coronal mass ejection that was emitted from the Sun on Friday.
