How long will the solar storm last?

The solar storm is expected to linger throughout Thursday, with potential for continued disturbances into the evening in some regions. NOAA notes the storm's strength has fluctuated from G3 to G1 before rising again to a G2 level.

What is the 'South Atlantic Anomaly' and how does it affect Earth?

The South Atlantic Anomaly is a growing 'weak spot' in Earth's magnetic field that allows harmful radiation to come closer to the planet's surface. This can interfere with satellite operations and data collection, potentially worsening the effects of future solar storms.

Powerful Solar Storm Disrupts Power Grids and Satellites Across North America

A major solar storm is currently striking Earth, disrupting the planet's magnetic field and putting power grids, satellites, and GPS systems across the northern United States at risk. The G3-level geomagnetic storm, considered 'strong,' began late Wednesday night and is expected to linger throughout Thursday.

The storm's effects peaked between 1:27 AM and 2 AM ET on Thursday morning, but the National Oceanic and Atmospheric Administration (NOAA) notes the solar event is still at G2 strength heading into the afternoon. This storm is the result of multiple solar eruptions, including flares and coronal mass ejections, that have been detected since November 3rd.
