Second this post. A geomagnetic storm is NOT an EMP. I don't know why this got started. They're not the same at all.
Hell, even an EMP doesn't spell "the end of all transistors". That's a common journalist's meme, but these guys couldn't format a flash drive if
you paid them.
What happens with a solar/geomagnetic storm/CME are two main things: geomagnetic heave, and particle impact, with possible late trapping.
When the coronal mass hits the geomagnetic fan, the Earth's magnetic field starts a low frequency bucking motion, sort of like your hand does when
you hold it out the window of a car going down the highway. This oscillation in the field induces currents in long lines, like the ones used to
distribute high voltage AC between electrical grids in the US. This is called geomagnetic heave. The problem this causes is somewhat technical for
the average ATS user, but basically, the transformers they use are not designed to be able to deal with what is essentially a DC current superimposed
on the AC they're designed for. It causes the cores to saturate. When this happens, their inductance collapses, and they become what is known as
"short circuits". Then they burn up. It's not because of super solar power getting into them, it's because they become unbalanced and walk off
their B-H curves, quit being transformers, and become loads.
There are ways to stop this, and it costs money, so they don't do it, because they plan to just shut down long lines during the worst bits. It's a
bad gamble.
The other thing you have happen is damage to satellite assets due to direct impact by the incoming particles, and magnetospheric trapping which causes
the incoming particles to loop in big circles at hellacious speeds, giving them lots and lots of passes at your satellites for a week or two after the
event is over.
For the first part, you have some shielding on the satellites, but not a lot. It's best to just shut them down temporarily to prevent logic level
upset damage. There's not a lot you can do about crystal lattice damage to solar cells, or damage to FLASH or EEROM data by x-ray bursts caused by
Bremsstrahlung radiation secondary to impact with the satellite's skin and framework.
For the second part, you either wait it out or you can purge the magnetosphere of those particles going in loops using a really neat trick which HAARP
can do, also a few satellites the USAF put up a few years back. You could also do it from the Antarctic back a few years ago but they discontinued
that mission.
