The recent geomagnetic storm watch NOAA issued is rated as a G1. Auroras occur when solar wind interacts with Earth's magnetic field. The charged particles from the sun collide with gases in the ...

It is this geoelectric field, induced by the rapid change in the geomagnetic field near the surface, that causes GICs to arise in long conductors on the surface of the Earth. The ‘climatology’ of ...

When such solar activity is directed at Earth, the resulting geomagnetic storms can potentially ... The coronal hole are regions where the Sun's magnetic field lines open out into space, allowing ...

A huge 500,000 mile hole in the sun is set to blast Earth with geomagnetic storms that will hit this week ... The coronal hole are regions where the Sun's magnetic field lines open out into space, ...

The effects of a coronal mass ejection—a bubble of plasma that bursts from the sun’s surface—will likely impact Earth’s magnetic field on ... A minor or greater geomagnetic storm is ...

According to NOAA's Space Weather Prediction Center, the first of these two CMEs, from January 21, is set to score a 'glancing blow' on Earth's geomagnetic field late on Friday. As it sweeps past ...
