Terrifying solar storm cracks open Earth’s magnetic field

After a brief period of quiet, the Earth has been bombarded with solar particles that have sparked a terrifying solar storm event. Interestingly, the solar storm was not triggered by a coronal mass ejection, which is usually responsible for such events. Instead, it was caused by the solar winds. Reports suggest that multiple solar winds smacked into the Earth's magnetosphere, causing it to weaken and cracks to open up in its structure, an occurrence known as a co-rotating interaction region. The crack allowed solar winds to spark the solar storm.

As per a report by SpaceWeather.com, “Earth's magnetic field remains unsettled on June 16th following yesterday's impact of a co-rotating interaction region (CIR). CIRs are transition zones between solar wind streams. Solar wind plasma piles up in these regions, producing shock-like structures that mimic CMEs. The impact on June 15th opened a crack in our planet's magnetic field and sparked a G2-class geomagnetic storm”.

Co-rotating Interaction Regions (CIR) are caused when fast-moving solar winds from different directions strike the Earth, stretching apart its magnetic field and creating cracks on it. The magnetosphere eventually recovers, healing these cracks on its own.

However, with the Sun nearing the peak of its solar cycle, such cracks can have a devastating effect as they amplify the intensity of the solar storm. If it was a powerful CME cloud, it could have produced a severe solar storm. A severe solar storm can even interrupt mobile data, and internet reception and cause power grid failure.

One of the major entities that observe and predict such atmospheric disturbances is the National Oceanic and Atmospheric Administration. It has an arsenal of satellites floating around
