Geomagnetic Storm Brings Dazzling Northern Lights To U.s. Skies

A surge successful energized star particles hurling towards nan Earth is lighting up nan skies arsenic acold southbound arsenic Florida pinch dazzling displays, which meteorologists opportunity is powerful capable to sound retired a fewer radios.

The red, purple and greenish hues colored skies successful Alabama, Ohio and Texas, and forecasters astatine nan Space Weather Prediction Center person said nan geomagnetic large wind could intensify arsenic nan "final and astir energetic CME," meaning coronal wide ejection, is yet to get and could scope Earth connected Wednesday afternoon.

A CME is an eruption of monolithic clouds of protons, electrons, and magnetic fields from nan Sun’s outer ambiance astatine very precocious speeds.

When it reaches nan Earth’s magnetic field, besides called nan magnetosphere, it collides pinch nan particles astir nan planet, producing colorful ray known arsenic aurora borealis successful nan bluish hemisphere and aurora australis successful nan confederate hemisphere.

Shawn Dahl, a forecaster astatine NOAA’s Space Weather Prediction Center successful Boulder, Colorado, said 2 CMEs had already reached Earth, resulting successful a geomagnetic large wind which reached G4 — nan second-highest standing connected a five-step scale.

The wide spot of nan magnetic section from nan passing CMEs was "not only 8 times stronger than what’s normal but is besides favorable astatine nan infinitesimal for continued activity,” Dahl said successful a video posted connected X.

Forecasters warned nan magnetic large wind could origin powerfulness fluctuations, GPS degradation and intermittent disruptions to radios.

“Watches astatine this level are very rare,” nan Space Weather Prediction Center said successful an advisory.

“We judge that nan ‘heart’ of nan existent CME — nan magnetic unreality — is passing complete nan Earth and will proceed to do truthful done nan overnight hours,” nan agency said early Wednesday.

With nan third, stronger CME expected to scope nan Earth connected Wednesday, an aurora could beryllium visible moreover further south.

While nan second-highest level advisory was still successful effect for different fewer hours, Dahl said it was imaginable this could scope G5, nan highest rating.
