The Northern Lights are caused by the solar wind, a stream of charged particles from the sun interacting with Earth’s ...

Scientists at NASA and NOAA think the sun has reached the maximum phase of the solar cycle, which means another year — at least — of intense Northern Lights.

This stunning light show was triggered by a G4 geomagnetic storm caused by a plume of solar plasma ejected from the sun.

Geomagnetic storms are measured on a scale of G1 to G5, with G5 being the most powerful and least commonly seen. At its solar ...

which—for geomagnetic storms—runs from G1 (minor) to G5 (extreme). While the storm back in May was classified as a G5 (extreme) storm, the latest storm peaked at a G4 (severe) event.

Geomagnetic storms are measured on a scale of G1 (minor) to G5 (extreme), with G5 storms being the least common but most ...

In May a large and complex sunspot cluster produced strong solar flares that formed an extreme geomagnetic storm, the strongest in 20 years - with the highest G5 rating given. The spectacular ...

Extreme events (G5 on the NOAA scale) are much less common. On average, there are 4 occurrences of G5 geomagnetic storms per solar cycle, which is about 0.1 percent of the time. Even among these ...

Displays of Northern lights are possible on Sunday night across the Northern U.S. due to a geomagnetic storm underway.

Fox Weather reported that Sunday night had the potential for the Northern Lights to reach US states like New York due to a ...

After reaching solar maximum in Solar Cycle 25, the Sun continues producing multiple solar flares, with some Earth-directed ...
