The medium sized ‘M-class’ (Mid-sized solar flare) solar flares can release enough charge particles to strip electrons from the earth’s ionosphere blocking communications signals to and from the satellites. The ionosphere also begins bouncing off the particles and waves back into space colliding with the satellites communication waves and momentarily interrupting signals between the satellites and earth.
When a large ‘X-class’ (largest of all solar flares) solar flare occurs it carries enough charged particles, x-rays and magnetized plasma that although is harmless to humans due to the atmosphere protection, can have an electromagnetic pulse effect (EMP) on the Earth causing all electronically powered sources to be forcedly shut off for anywhere up to a few years (in the event of a severely large solar flare) which would stop almost all industries from continuing work and cause chaos on as no electrical appliances in which we thrive off would
