An "extreme" G5 geomagnetic storm reached Earth on Friday, NOAA's Space Weather Prediction Center said, after issuing a watch earlier in the day warning of the potential for a severe impact.

(NEXSTAR) — On Friday night, the most significant G5 geomagnetic storm since 2003 hit Earth — causing several coronal mass ejections, or CMEs — and allowing many across the U.S. to see ...

Aurora chasers, keep your eyes on the skies this weekend as northern lights might be possible at mid-latitudes.

Northern lights may once again be visible deep into mid latitudes tonight as geomagnetic storm conditions continue to wreak havoc with Earth's magnetic field.

NOAA classifies geomagnetic storms on a G-scale, with G5 being the most severe. The current watch is for a G2-class storm, which is considered moderate. How dangerous are solar storms?

Colorful auroras could be visible in areas of the United States such as Alabama and Northern California — much farther south than they typically appear — on Thursday evening due to a powerful solar ...

Historically, G4 storms are common during a solar cycle, but G5, or extreme geomagnetic storms such the one that occurred on May 10, are incredibly rare, Dahl said. This new storm has a 25% chance ...

Space weather experts warn that a "moderate" geomagnetic storm could rock Earth over the weekend, potentially lighting the ...

At high altitudes, geomagnetic storms can also result in stunning displays of light called auroras. The NOAA Space Weather Prediction Center ranks geomagnetic storms on a scale of G1 to G5.
