(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 ...

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 ...

"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.

The NOAA reported that a storm of this magnitude could create “Detrimental impacts to some of our critical infrastructure technology.” In the past, the extreme (G5) geomagnetic storm of 2003 ...

Whether 3664 will be able to stir up another G5 geomagnetic storm remains to be seen, but since it fired off an X-12 flare while it was around the backside, you never know. Your best bet to stay ...
