Geomagnetic storm lights up U.S. skies after powerful solar flare
Summary: A geomagnetic storm occurred over the first weekend of October, causing bright displays in parts of the U.S. The storm originated from a solar flare on October 3, which was the strongest recorded by South Africa's National Space Agency in seven years.
The solar flare briefly disrupted high-frequency radio communications in Africa, leading to a 20-minute blackout. The coronal mass ejection from the flare reached Earth on October 8, causing the geomagnetic storm.
Geomagnetic storms are common and can affect technology, particularly power grids and satellites. Monitoring systems are in place to provide early warnings, helping to mitigate potential damage to infrastructure.
