Earth Barely Dodged Solar Blast In 2012
Rambo Tribble (1273454) writes "Coronal mass ejections, with severity comparable to the 1859 Carrington event, missed Earth by only 9 days in 2012, according to researchers. The Carrington event caused widespread damage to the telegraph system in the U.S., and a similar occurrence would be devastating to modern electronics, it is thought. From the Reuters article, 'Had it hit Earth, it probably would have been like the big one in 1859, but the effect today, with our modern technologies, would have been tremendous.' The potential global cost for such damage is pegged at $2.6 trillion."

What..
Yeah, I know, I'm being a bit picky here, but... dodged?
The CME barely missed; Earth didn't do anything, the lazy git.

1. Knowing something is possible is better than not knowing
2. We can't mitigate it? Turn in your nerd card right this instant
3. Who is panicking?
4. You'd rather this get submitted to some non-nerd website? I agree that seeing grandmothers starting to wear tinfoil hats to avoid solar flare problems might be really really funny, but this is exactly the type of submission for slashdot and vice versa.
5. I find your sig ironic in this context.
Proofread! You're shit!
You're a temporary arrangement of matter sliding towards oblivion in a cold, uncaring universe
Really good.
And many supplies have MOVs and LC networks that would help mitigate the problem. In the old days, telegraph wires weren't earthed, and so became enormous antennas that could readily be charged by ionization.
Satellites are less protected, and there, sensitive low-power (especially CMOS) products might easily fry. However, they're already shielded and exposed to the elements in a way unlike us on the ground.
We're smart enough to tie most neutrals to earth in home wiring boxes. OTOH, the skin effect could fry stuff. Your car's ECM might be just fine because it's under a metal hood, albeit insulated from the earth by the tires. As such, it's not really a capacitor or joule/coulomb tank.
Major electrical grid problems would ensue, but recovery might not be as tough as you think.

Think. I know it's hard, but try it. We're not talking about magic here. The car does not have an antenna hundreds of km to over a thousand km long. Electric fields are measured in volts per meter, not volts per fairy tale.
Inducing a 20 mA current in a telegraph line hundreds of km long (which is all it takes to "tap away") is slightly different from inducing tens to hundreds of thousands of amps for tens of seconds to minutes. That's what it would take to "fry" the windings in a starter or alternator. And the antenna length of the wiring attached to the starter or alternator is no more than a couple of meters, INSIDE a faraday cage.
An ignition coil would take less current to burn out than a starter or alternator, but still a whole hell of a lot more current than it would ever see inside the faraday cage of the car body.
The problem is not so much end-user equipment, although that alone would be pretty devastating to most people. The real problem is the destruction of the electrical grid that would result. Most of the large transformers and relays are custom-made one-off pieces, and backorder time for them under normal circumstances is 3 months to 2 years. There are no procedures available to collapse the grid in preparation to a CME to protect that equipment, it's really not doable at this point. Imagine most of North America without electricity for a series of months. Electricity is used to pump natural gas around the country, so most of that's unavailable. Electricity is used in gas pumps, so even if your car still works you have no fuel for it. Farmers have the fuel in their tanks, but after that their tractors are going to be parked for the duration. Many railroad switches can no longer be thrown by hand and schedules are all computerized, so big chunks of the rail network are going to be down. Most hospitals have 3 days of fuel for their generators, beyond that they're back to doing surgery by candlelight.
The repercussions are enormous.

Probably because the electrical grid is controlled by for-profit corporations run by executives hyper-focused on short-term revenue to get their next bonus.

Sometime back some small solar wind even knocked out a satellite. Normally it would not even be a blip in the radar. But that satellite was the link to credit card processing in the pay-at-the pump gas stations. Almost all these gas stations have cut down their employee down to one guy who sells chips and soda. Almost all the bays are self service. When the pay at the pump payment system got knocked out, people had to fill the car and walk in to pay that lone guy. Lines started forming, then the lines stretched, and reached the exit ramps of highways, and the highway started getting blocked. But at the end, after the mess cleared, still there is no incentive to create alternate routing or redundancy in the system.
It costs money to make things secure. To make things robust. But if some company does it the right way and it competes with another company that does not, it is not going to be competitive. Yes, in the long run, catastrophe will strike and the chickens will come home to roost and the corner cutters would find themselves getting the short end of the stick. But, the non-corner-cutter could have been driven out of business before the catastrophe strikes.
So it all depends on the frequency of the odd ball event. If the odd ball event is less frequent than once in a decade, there is no structural incentive for any manager to do the right thing. Most people change jobs once a decade and they will not be there to face the music. This is a systemic structural thing. The race to the bottom is the only race there is.
It might not be a solar storm, or a terrestrial storm. It could be some fiber optic cable being accidentally severed. Or sabotaged. Or an oil spill blocks rail traffic somewhere. So don't think it is mere fear mongering or rationalize it saying solar storms are rare. Systematically our infrastructure has become very vulnerable without redundancy without factors of safety.

One of the potential scenarios the US military does prepare for is loss of power to our power grid due to cyber attack so they are prepared. The US military partly exists for disaster response and there are several commands dedicated to it. Provided their already shielded equipment isn't taken out, they could have lines of communications established for government in a matter of days. They would most likely be given priority for resources if everything were wiped out and their ability to adapt to equipment issues both on the power generation and communications side is actually quite impressive.
