The Sun is going through an active phase experiencing a number of eruptions, called Coronal Mass Ejections. These send solar particles towards the Earth.
When there are a large number of these particles, they can overwhelm the Earth's natural protection and break through its magnetic shield. They then hit the upper atmosphere at the north and south poles. It is the interaction of these particles with the Earth's atmosphere that create the stunning light displays we see in the night sky, called the Aurora Borealis. unfortunately, here in Cyprus, we are too far south to see them, but those in the UK will
Geomagnetic storms are disturbances in the Earth's magnetic field that last minutes or hours and are caused by Coronal Mass Ejections (CMEs) and solar flares.
It has been reported that there are three CMEs heading towards Earth from the Sun.
The National Oceanographic Atmospheric Administration Space Weather Protection Centre (NOAA: www.swpc.noaa.gov), who measure the strength of these storms, say that there is chance of a Strong G3 or even Severe G4 geomagnetic storm being triggered especially on Wednesday into Thursday.
Although dangerous for astronauts, geomagnetic storms are not harmful to humans as Earth's atmosphere protects us from the radiation. But... it can disrupt mobile phone signals, satellite bavigation systems like GPS in your car and even electrical power grids.
