Appearing as cooler, dark patches when viewed in extreme ultraviolet and soft X-ray images of the sun, coronal holes are caused when the local magnetic field opens up, allowing the solar wind to ...

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. Coronal holes are regions where the sun's ...

Two giant holes in the Sun could create impactful space weather for Earth in early February. Recent NOAA satellite images show two coronal holes, areas on the surface of the Sun with cooler plasma.

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 ...

NOAA Coronal holes form in the outermost layer of the sun when the local magnetic field opens up, allowing the solar wind to escape at a much faster rate than usual. Because of this escaping ...

The Met Office has issued an update on the aurora forecast, with the Northern Lights possibly being visible in parts of the ...

An increase in auroral activity is likely the result of expected geomagnetic storm conditions caused by a coronal hole high-speed stream, or winds from a cooler, less dense area on the sun’s ...

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 90 per cent chance of aurora for northern parts of the UK.

In their full forecast from today, March 7 until March 10. The Met Office states: "Background solar winds are expected during ...
