X-class flares will have a more destructive potential than the other classes of flares. When a Coronal Mass Ejection charged particles interacts with the Earth’s magnetic field, they could produce geomagnetic storms that are powerful enough to interfere with GPS signals, power grids and radio communications.
We are to expect more activity from the sun over the coming years.
Hello Oranumpsychic,
Yes you are quite correct, there can indeed be extensive radio interference plus internet and power outages. We lost internet and 3G connection for a few hrs and and it has been very patchy for the last 24hrs here in Costa Rica.
Always be prepared.
Keep well :D
