Government Agency Warns of ‘Severe’ Geomagnetic Storm Alert
A federal weather agency has issued an alert stating that a “severe” geomagnetic storm is impacting Earth on Sunday and will last until Monday.
The National Oceanic and Atmospheric Administration (NOAA) Space Weather Prediction Center has warned of a “major disturbance in Earth’s magnetic field” occurring on Sunday, issuing a G4, or “severe,” geomagnetic storm alert.
A solar coronal mass ejection arrived around March 24, resulting in “severe (G4) geomagnetic storming observed and expected to continue through the remainder of Sunday and into Monday. The impact on satellites or telecommunications is unclear.
“The public is not expected to experience adverse impacts and no action is required,” the agency stated. However, staying informed of storm progression by visiting their webpage is recommended.
Operators of infrastructure have been notified to mitigate possible impacts such as “frequent voltage control problems.” There is also an “increased possibility of anomalies” to satellites, with “more frequent” periods of GPS degradation possible, according to NOAA.
However, it remains uncertain if the aurora borealis will be visible in the lower 48, as Eric Snitil, chief meteorologist at WROC-TV in Rochester, New York, stated that the northern lights may be visible if the storming continues into the night. He added that a G4 storm means residents as far south as Alabama and California could see them.
“As we approach the peak of Solar Cycle 25, we should expect to see more sunspots, each of which is a region of intense magnetic activity capable of producing solar flares and coronal mass ejections, or CMEs,” NOAA explained. “This period of elevated activity can last up to several years, with impactful space weather events possible in 2024.”
Over time, there have been warnings that highly potent solar flares could lead to widespread disruptions on Earth. Researchers suggest that such an event could cause global chaos due to severe impacts on electronics, telecommunications, and power grids worldwide.
