A federal weather agency has issued an alert stating that a severe geomagnetic storm is currently impacting Earth and is expected to last until Monday. The National Oceanic and Atmospheric Administration (NOAA) Space Weather Prediction Center issued a G4 geomagnetic storm alert, warning of a major disturbance in Earth’s magnetic field.
The storm, caused by a sun coronal mass ejection that arrived around March 24, has resulted in severe geomagnetic storming that is expected to continue through Sunday and into Monday. While it is unclear if the storm has caused any damage to satellites or telecommunications, the public has been advised that no adverse impacts are anticipated, and no action is necessary. However, individuals are encouraged to stay informed of the storm’s progression by visiting the agency’s webpage.
Operators of infrastructure have been notified to take action to mitigate possible impacts such as frequent voltage control problems. There is also an increased possibility of anomalies to satellites and more frequent periods of GPS degradation. The University of Alaska Fairbanks Geophysical Institute’s website has forecasted high aurora borealis activity until Monday evening, with visibility expected in various parts of the United States.
According to NOAA, a geomagnetic storm signifies a disturbance in Earth’s magnetosphere caused by solar wind energy impacting the planet’s surroundings. The most recent solar flare that triggered the current geomagnetic storm occurred as the sun was approaching the peak of its current cycle, which started several years ago.
Experts warn that extreme solar storms could have significant impacts on Earth, potentially causing widespread disruptions to electronics, telecommunications, and power grids. Such events could lead to worldwide chaos and severe radiation risks to astronauts. As we approach the peak of Solar Cycle 25, NOAA anticipates more sunspots and intense magnetic activity, with impactful space weather events possible in 2024.
