Forecasters said a coronal hole high-speed stream—winds from a cooler, less dense area on the sun’s surface—will likely result in a geomagnetic storm later Friday, marking a disturbance in ...

A strong solar wind from a coronal hole — a dark area in the Sun's corona that allows wind to escape into space at high speed — is heading toward Earth and is expected to cause a minor ...

Thanks to a high-speed solar wind streaming from a massive coronal hole in the sun, a geomagnetic storm could set the stage for a dazzling display of the aurora borealis on Feb. 14, 2025.

A colossal coronal hole, nearly 500,000 miles (800,000 kilometers) wide, has opened in the sun's atmosphere, spewing fast-moving solar wind toward Earth. The solar wind escaping from this coronal ...
