On Tuesday, NOAA issued a G4, or severe, geomagnetic storm watch in response to recent coronal mass ejections, or CMEs, from the sun. CMEs are huge bubbles of coronal plasma that the sun occasionally ejects, NASA says. The highest geomagnetic storm level is G5, which is considered extreme.

Nature offers many dazzling displays, from jagged flashes of lightning to radiant sunsets. But perhaps one of the most elusive natural phenomena is the shimmering waves of green, pink, and red dancing across the night sky,

After displays of auroras lit up the sky on Tuesday, another Northern Light array is expected to bring a gleaming light show to the northern part of the U.S. Wednesday.

Strong geomagnetic storms and a moderate solar radiation storm have led to an aurora view forecast for Wednesday night in the northern U.S.

Skies over North America erupted this week with shimmering colors: Shades of pink, purple and green swayed across the skies in Northern as well as some Southern states. It followed two similarly prolific auroral displays in North America in October and May of 2024.

Bands of green and red first pierced through the hazy night sky around 9:30 p.m. above the pier at Grand Haven State Park.

The Statesman collaborated with readers to gather photos of the aurora borealis throughout Central Texas. Here are the eerily beautiful results.

Coronal mass ejections, or CMEs, are large clouds of ionized gas called plasma and magnetic fields that erupt from the sun’s outer atmosphere. When these outbursts are directed at Earth, they can cause major disturbances of Earth’s magnetic field, resulting in geomagnetic storms.
