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.

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.

Illinois residents hoping to see the Northern Lights this week could have a golden opportunity as the Space Weather Prediction Center issued a “very rare” G4-class geomagnetic storm watch.

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 ...

A "severe" G4-scale geomagnetic storm hit Earth this morning following a series of powerful solar eruptions, the National Oceanic and Atmospheric Administration (NOAA) announced. The storm has since ...

Recent solar activity has triggered a severe G4 geomagnetic storm, causing auroras to appear worldwide and with more possibly visible tonight.
