But also ground-based medical imaging systems, chronic illness monitoring devices, and pregnancy-related diagnostic equipment that rely on uninterrupted signals.
Professor Sean Elvidge, an expert on the space environment from the University of Birmingham, told MailOnline: “Filament eruptions, also known as Coronal Mass Ejections (CMEs),
Occur due to instabilities in the Sun’s magnetic field. “These instabilities trigger large-scale expulsions of magnetic field structures and plasma into space.
These eruptions vary greatly in speed and size, some rapidly traveling outward at nearly 3000 km/s.” During an eruption, filaments of cooler plasma become suspended.
Above the sun’s surface by powerful magnetic fields. In images of the sun, you can see these filaments as long, dark sections shifting over the surface. When Solar Filaments Break Free
But when the magnetic fields weaken, these filaments can suddenly break free in a violent eruption. It is the arrival of these waves of material in the CME which triggers geomagnetic storms.
