A huge sun eruption combines with speedy solar wind from a "coronal hole" for a weekend aurora show, experts predict.

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 ...

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 ...

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.

The high-speed solar wind originating from this coronal hole, imaged here on Oct. 10, 2015, by NASA's Solar Dynamics Observatory, created a geomagnetic storm near Earth that resulted in several ...

It indicates that the aurora may occur halfway between the green and yellow lines in the below image: These solar winds are coming from a giant coronal hole on the sun. The giant dark spot is not ...

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 ...

Coronal holes across the sun can influence India’s monsoon rains. These holes release high-speed solar wind, which interacts with Earth’s magnetic field, potentially affecting rainfall patterns, ...

The above image, provided by the Met Office shows northern parts of the UK under a red colour. The colour indicates a chance ...

NASA's Solar Dynamics Observatory (SDO) spacecraft picked up on the activity and its mission is to study the Sun’s dynamics to "increase understanding of the nature and sources of solar variability".
