The gigantic coronal hole is blasting high-speed solar wind toward Earth, potentially igniting vibrant auroras and minor geomagnetic activity on Jan. 31. and Feb. 1. Keep up with current northern ...

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.

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 ...

Could coronal CT reconstructions, incorporating measurement of craniocaudal dimensions, further enhance precision, thereby optimizing treatment outcomes? To determine if coronal CT imaging ...
