A massive solar eruption from sunspot 4100 has launched a fast-moving CME toward Earth, with G4-class geomagnetic storm ...

EDT on June 1, 2025, instruments registered a geomagnetic K-index of 8, creeping toward 9, meaning a solar storm has arrived.

The structure of one of the ejections has captured the attention of the scientific community due to its potential for ...

In the aftermath of a one-two punch of solar flares hitting the Earth, experts warn that earthlings are unprepared for more ...

According to NASA, solar radiation storms or solar flares occur when a large-scale magnetic eruption causes a coronal mass ...

The flare lasted for three hours, which is longer than usual. While it didn't attain a high intensity, it did eject a significant amount of mass that could cause considerable disruption.

The impact, which has been termed a halo Coronal Mass Ejection (CME), has been significant even as the storm subsides.

A strong solar storm is currently impacting Earth. The event, triggered by a major solar flare, may cause widespread auroras. Satellite and GPS interference are possible. Power grid instability is ...

The impact is expected to spark a severe (G4-class) geomagnetic storm, raising the possibility of dazzling auroras visible ...

A powerful coronal mass ejection (CME) is predicted to hit Earth today, potentially triggering a severe geomagnetic storm and spectacular auroras.

Aurora displays known as the northern and southern lights are commonly visible near the poles, where charged particles from ...

Forecasters of space weather keep an eye on the sun to stay ahead of eruptions of solar material that have the ability to shut down power grids on Earth, disrupt aircraft routes, global communications ...
