I've been wondering what was wrong with me. With all due and undue respect Ratty, you are still breathing. According to Extinction Rebellion, that is your major ailment. And ANTIFA knows how to fix that ... if they could ever get out of their parent's basement.

Nothing to do with the cold weather of course

THE GREAT GEOMAGNETIC STORM OF MAY 1921 - You think Covid-19 is bad? Imagine one of these in our electrically driven World. How long would that take to fix with no in-place protection. Can you say ... Game Over. My Grandparents farmstead was not electrified till the late 1940s. Their farm equipment was a mule. They probably didn't even notice. Who in the Western World could say that today? The Vietnamese might laugh at us though. Some engineer please tell me I'm wrong. (Engineering report included) spaceweather.com/It began on May 12, 1921 when giant sunspot AR1842, crossing the sun during the declining phase of Solar Cycle 15, began to flare. One explosion after another hurled coronal mass ejections (CMEs) directly toward Earth. For the next 3 days, CMEs rocked Earth’s magnetic field. Scientists around the world were surprised when their magnetometers suddenly went offscale, pens in strip chart recorders pegged uselessly to the top of the paper.
Then the fires began. Around 02:00 GMT on May 15th, a telegraph exchange in Sweden burst into flames. About an hour later, the same thing happened across the Atlantic in the village of Brewster, New York. Flames engulfed the switch-board at the Brewster station of the Central New England Railroad and quickly spread to destroy the whole building. That fire, along with another one about the same time in a railroad control tower near New York City's Grand Central Station, is why the event is sometimes referred to as the "New York Railroad Superstorm."
What caused the fires? Electrical currents induced by geomagnetic activity surged through telephone and telegraph lines, heating them to the point of combustion. Strong currents disrupted telegraph systems in Australia, Brazil, Denmark, France, Japan, New Zealand, Norway, Sweden, the UK and USA. The Ottawa Journal reported that many long-distance telephone lines in New Brunswick were burned out by the storm. On some telegraph lines in the USA voltages spiked as high as 1000 V.

The big problem for recovery is that big transformers would be taken out and there are very few spares. So the system would need to bootstrap up by choosing an industrial center that could make new transformers. Then take working transformers off line and any spares then transporting them to the bootstrap location. That location ideally would be close to surviving gas or coal generation in the hope of getting sufficient baseload power to create new transformers. All the while fighting off rioters and looters.

You seem interested suddenly? Spaceweather sent me an email ... and I thought it was the least I could do. AND ... I'd never heard of the 1921 event before. The rest of it I blame on GDS.

With bitcoin, he does have money to burn doesn't he? He's into EXTREME Fractional ownership. I tend to keep everything as electronic copy as it is a lot easier to carry around than a briefcase of paper. Other half is the opposite everything is written down and computers eyed with some suspicion. Every time there is a glitch or the power goes down the Carrington Event style warnings of what will everyone do if the power stays down for a while? And it is obvious that in the space of ~40 years computers have gone from a black art for the geeks to something everyone carries around in their pockets with their entire life from banking to family photos stored on them. There are 40 year olds that have never known a life without computers. It is probable that there could be an intense CME in our direction one day and it will fry a lot of electronics. For many people that will be the literally end of life as they know it. So apart from the larger issues of existence their entire electronic life will disappear in seconds.

Quick note on CME's; as with most things, they aren't binary. CMEs happen all the time *in varying strengths*. They're also rather directional and the Sun isn't *trying* to hit us, so any given CME has a tiny chance of hitting the Earth.
A minor CME might fry some lightly shielded equipment and perhaps some satellites. A medium one would still leave inactive, unconnected equipment or heavily shielded systems intact. Even the heaviest ones recorded are going to have a hard time killing something in a Faraday cage.
Nowadays there are various ways to harden and protect equipment from HIRF/EMI; which is a good thing because the world is full of that noise all the time. I have no idea how 'hardened' the average smart phone is (I suspect not very), but a commercial airplane can actually take quite a bit of energy and keep on flying. If you're curious about how much, find yourself a copy of RTCA DO-160.
Of course, as with any contest between armor and warhead, the warhead always wins in the end if it tries hard enough. But the Sun doesn't try that hard very often, and as noted the Earth is a small target. We might all be dead before something like the Carrington event happens again.
Of course, after all that reassurance I feel obligated to note that it *is* one of the natural disasters I prep for... :-}

For example, how exactly is a house's internal wiring and attached components effectively protected from grid surges or more direct effects of a 1921-scale event?

I should have added this to my first post as it answers your questions First this house is built 'above code' which in Florida largely refers to hurricane proofing building code. The builders claim that this house should withstand a Cat 3 with only minor damage and still be a house after a Cat 4. As part of that there are steel straps/bars going from the steel mesh in the concrete float below the house up and over the underlying roof and down the steel mesh in the concrete float on the other side of the house. These are every 18" and the unintentional Faraday cage successfully attenuates all cellphone signals I suspect it would have a similar although not so successful effect on a solar event - but who knows. A Cat 2 went directly over the house 3 months after we moved in and we have had several close brushes with Cat 3 and so far the builder has proved correct. The other weather we get continually are thunderstorms (part of hurricanes as well) so the local power company Florida Power and Light provides whole house power spike protection that smooths power if there is a nearby lightning strike. Around 10 years or so ago there was a direct strike on a palm tree 10 feet from the house it did a real number on a pool blower pump that was close by but had there was no effect on the house power that carried on as normal. The FPL engineers did have to replace the whole house smoother though. Of course everything internally is on smoothers and UPSs. Now all I have to do is wait for a Carrington Event and see what happens then
