A huge eruption of filament from the Sun’s outer layer on May 7 has shot out an alarming coronal mass ejection (CME) that is set to strike Earth’s magnetic field, which could spark solar storms once it arrives. A CME is a huge bubble of plasma shot out from the Sun which contain billions of tons of fast-moving solar particles as well as the magnetic field that binds them.

 

NOAA analysts have warned that the incoming CME might deliver a “glancing blow” to Earth’s magnetic field on May 10, with possible minor geomagnetic storms a potential consequence of the rapid solar wind’s impact. 

US Space Weather Center (SWPC) ranks solar storms on a scale of “G1 Minor”, the least intense, all the way up to “G5 Extreme”.

But even the weakest of storms threaten “power-grid fluctuations” and have a “minor impact on satellite operations”.

This is a breaking story. More to follow.
