That event was the third geomagnetic storm to reach G4 status during the current 11-year solar cycle, which began in 2019, according to the SWPC. At that time, the agency said the event posed no ...

Along with the G4 storm, the SWPC said the CME headed for Earth will also bring with it an S3-level solar radiation storm, which could harm astronauts and passengers on high-flying aircraft ...

G4 is the second-highest grade of geomagnetic solar storm and additional solar disruptions may cause continued geomagnetic storm conditions through the weekend, according to NOAA.

If you've never heard of a solar storm or geomagnetic storm, chances are you'll learn about those really quickly this weekend. Earth is under a severe G4 watch or geomagnetic storm watch for the ...

The "severe" G4 geomagnetic storm sparked auroras across the U.S. on Thursday night, with less powerful but still significant solar storms expected to continue throughout Friday.

Crucial Quote. Solar activity is cyclical and intensity varies over a period of around 11 years. “G4 storms are relatively rare, with about 100 over the course of an 11-year solar cycle,” Rob ...

A G4-level solar storm, such as the one expected to hit as soon as Friday evening, can cause issues with the power grid, radio communications and the accuracy of GPS.
