Astronomers warned last year in a report by news agency Bloomberg for our excessive dependence on satellite data, which can be affected by a so-called solar storm. Even the Danish saxo bank, predicted that this year's increased solar activity, severe damage could do to satellites, telecommunications and power grids. But as far as we are fortunately not yet.
What is a solar storm? And how is that?
The sun may produce solar flares and plasmawolken, and winds in addition to magnetic fields and all sorts of charged particles into space. Usually we find a few of these solar storms, except by the colorful Northern lights around the poles, caused by charged particles that collide with the upper atmosphere.
