High-speed winds from a spot on the sun’s surface may affect Earth’s magnetic field, pulling the phenomenon further south.

These dark areas on the Sun, as seen in satellite images, can produce space weather events known as coronal hole high-speed streams (CH HSS), which can trigger Northern Lights on Earth.

The wind is billowing out of a hole in the sun's upper atmosphere ... dark patches when viewed in ultraviolet and soft X-ray images of the sun. Coronal holes may superficially appear to be ...

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 ...

During March and September equinoxes, Earth's axis is parallel to the sun's. Magnetic fields of Earth and the solar wind momentarily coincide, creating "cracks" that allow charged particles to ...

According to Met Office aurora maps, the best time to see the Northern Lights at the weekend is 9.00pm UK time, with up to a ...
