A new study demonstrates how an interplanetary coronal mass ejection (ICME) clears the path for following transients and ...

In a paper published in Earth and Planetary Physics, researchers propose a semi-empirical model combining Burton's empirical ...

The CME arrived at Earth on Sunday, producing a "severe" (level G4 out of G5) geomagnetic storm, causing disruptions to the planet’s magnetosphere and triggering displays of Northern Lights as ...

A severe geomagnetic storm reached Earth on Thursday, which could bring an increased chance of auroras and may affect communications and the power grid.

A "severe" G4 geomagnetic storm could make auroras visible across the country Thursday, according to forecasters with National Oceanic and Atmospheric Administration.Here's what we know about the ...

Keep reading to learn when the G4 geomagnetic storm is expected to hit Earth, and where you need to be to get a glimpse at the magnificent auroras it will undoubtably produce.

Massive geomagnetic storm could make Northern Lights visible Thursday The storm was upgraded to a G4 classification Thursday afternoon ...

The geomagnetic storm is expected to be a G4 class, according to the scale used by the U.S. National Oceanic and Atmospheric Administration (NOAA)'s Space Weather Prediction Center (SWPC).

NOAA's Space Weather Prediction Center (SWPC) said that the severe (G4) geomagnetic storm could affect the power grid, as well as GPS and radio blackouts and impacts on satellites.

While geomagnetic storms reaching G4 strength have been known to bring the northern lights to much of the country — at times as far south as Alabama and northern California — it’s unlikely ...
