a nuclear detonation in the upper atmosphere can produce an electromagnetic pulse (EMP) that can do exactly the same thing. If or when this ever happens in warfare you can bet they will blame it on a solar superstorm.A solar "superstorm" could knock out Earth's communications satellites,
cause dangerous power surges in the national grid and disrupt crucial navigation aids and aircraft avionics, a major report has found.
It is inevitable that an extreme solar storm
caused by the Sun ejecting billions of tonnes of highly-energetic matter travelling at a million miles an hour will hit the Earth at some time in the near future,
but it is impossible to predict more than about 30 minutes before it actually happens, a team of engineers has warned.
Solar superstorms are estimated to occur once every 100 or 200 years, with the last one hitting the Earth in 1859.
Although none has occurred in the space age, we are far more vulnerable now than a century ago because of the ubiquity of modern electronics, they said.
The magnetosphere and the ionosphere are supposed to protect us from these solar superstorms, however HAARP has been creating gashes in these magnetic fields making us more susceptible to the effects of solar EMP's.
