A severe geomagnetic storm caused by a coronal mass ejection from the Sun was detected by the Space Weather Prediction Center. The storm, rated "G4," is considered severe but may not guarantee the visibility of an aurora. The orientation of the CME's magnetic field relative to Earth's magnetic field is crucial for this phenomenon. Data suggests that despite the severity of the storm, an aurora may not be visible. The strength of the storm and its impact on Earth, such as anomalies or effects on satellite operations and GPS degradation, can fluctuate as the CME continues to affect the planet. More information will become available over time. The SWPC will monitor the situation closely to provide updates on the potential impacts of this geomagnetic storm.
