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

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

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.

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 ...

Like hurricanes, tornadoes, and earthquakes, the scale conveys the severity of a geomagnetic storm event, with G5 being the most extreme and G1 being minor. According to NOAA, the solar storm was ...

"The aurora may become visible over much of the northern half of the country, and maybe as far south as Alabama to northern California," NOAA predicted.

An ongoing severe geomagnetic storm could hinder recovery response to ... and rarest space weather conditions.The SWPC said extreme (G5) levels are possible. The solar storm is forecast to ...

The G4 geomagnetic storm is the second-strongest level and could be similar to the storm that brought the Northern Lights to much of the United States back in May. That storm was a G5. According ...
