Expert Predicts Solar Plasma ‘Spewing’ That Could Trigger Geomagnetic Storms on Earth

The UK’s meteorological agency (MET) said the CME might arrive on Saturday or earlier on Sunday.

There is an estimated 30 percent chance that it will cause a minor or G1 class hurricane, which will probably peak on Sunday, he said.

Geomagnetic storms are classed on a scale starting with G1 and working up from there, with G2 twice as strong as G1, and so on.

Class G1 hurricanes can cause minor fluctuations in the power grid, some effects on satellites as well as possible auroras.

There could be some more geomagnetic activity than expected if there was a second “coronal hole” taking effect at the same time,

The Met Office warned. It’s not clear how likely it is and when it might arrive, but it’s clear that the effect will only be small, he said.
