This paper estimates Kp = (8.4±0.8). Because the scale is logarithmic, the difference between 8 and 9.2 is obviously quite extreme. https://onlinelibrary.wiley.com/doi/pdf/10.1002/asna.2022007...
I'm sure there are articles discussing the point, but I wonder why citizen-facing scales don't use more linear representations for things.

It's a magnetic field, no? Is there any particular radioactive component? I'd be more worried about the acute effect on the plane's electronics, the whole point is they disrupt electrical systems.
https://www.swpc.noaa.gov/noaa-scales-explanation According to noaa there was an S2 Solar Radiations Storm and in the description for S2 it says: > Biological: Passengers and crew in high-flying aircraft at high latitudes may be exposed to elevated radiation risk. But the scale goes up to S5 and it the radiation will be higher for Austronauts, and for high flying aircrafts there is always a "may" attached.
Can you really call yourself a prepper if you don’t have a faraday cage with a spare laptop inside? (The intersection of doomerism and tech is amusingly cyberpunk sometimes.) Actually, what’s the most useful way you’d prepare for a worldwide grid outage? This isn’t that, but sometimes I wonder if a future CME might be as catastrophic as some say.
Of course if you're in Texas in midwinter when a CME happens, you are well and truly screwed.

Practice makes perfect. Highly recommend finding your local food not bombs cohort or visiting one in a nearby city and then starting your own back home. Community resiliency is a natural instinct it seems. Rebecca solnit's "paradise built in hell" is a fascinating read on the subject.
Now I’ve volunteered with a local FNB group so I’m not trying to be mean but… What would a group that gets cheap and or throwaway groceries and feeds homeless do in a Fit-Hits-The-Shan or End-of-World scenario? You’d have to hope some heavily agricultural minded types would be friendly to you and your labor potential.
Primarily volunteering with them creates two things that are basically the most important things in any emergency:
1. Knowledge of who to talk to and where to go when shit hits the fan
2. Established practices of organization
If community resources are scarce, and you have a FNB cohort in the community, you have a group of people with lots of practice stretching out food, preparing it, and redistributing it to many people. Again I recommend solnit, she wrote about this exact thing happening in one of SF's earliest devastating earthquakes.
The other upside is when the State turns up to fuck your community efforts up (like they did in SF, or Louisiana after Katrina) you also have a group with established methods of peaceful resistance. They probably already have clout with the local State enforcement group: the SFPD have gotten to the point where it's basically impossible to get them to harass FNB because of years of softening individual officers to the cause.
Edit: I see now you mean, practically speaking, what actions could they take.
Well in a place like NYC I have no idea. Probably there would be huge issues with famine. Realistically the first thing everyone should do is get the fuck out of that city lmao.
I don't know if SF would be so bad. There's also groups like Food Not Lawns trying to get people into growing their own food. If their efforts continue to be successful we can have closer to home food supply chains. As for convincing people to share, for some reason that isn't all that hard. When capitalism and its disincentives fall away, it seems people revert to our basic evolutionary advantage of social bonding and organization.
Not to mention all the dry goods stashed in stores throughout the city can be stretched pretty far by the people who have practice at it. If FNB minded folks can redistribute from the stores quickly enough they might even be able to get to the meat and etc to turn into jerky etc - hopefully they'd abandon veganism in an actual emergency. Knowing them, probably not lol. But if I'm there that's what I'm doing.
Others have written on the plight of cities in anarchy, and I don't think it's quite so doom and gloom. "Conquest of Bread" was the OG and I think it still holds up.
Should I disconnect my computer from the grid at this point? (I'm using a UPS with built-in power surge protection but I'd rather not test it in prod.)
They instead distort the geomagnetic field, and the changing magnetic field induces voltage. But the Earth's magnetic field is pretty weak, so the voltage becomes significant only for very large circuits. Such as transmission lines or old-style telegraph lines.

Nothing consequential for a single flight. Even crew really don't have to worry about it until it gets to very high levels, according to the NOAA scales
Do you have a source for this? My friend was asking about this.
As a comparison, a typical flight might only have a dose of 40uSv, so like 25 normal flights. But still many people take many more trips than that.

I used to be a logistics officer for an Infantry battalion. Most of the comments down thread underestimate water consumption. Depending on the climate, you'll want the following daily quantities [1]: - 2-3 gallons for drinking - 1.5 gallons for hygiene (can skip for a while) - 0.5 gallons for food prep The planning factor for military operations was 8 gallons per person per day. Water is heavy—8 pounds per gallon—and…
8 ga of water per person per day is completely insane in disaster scenario. 2-3ga for drinking a day? Medical professionals recommend less than 1 for a normal person.
A science presenter mentioned that the sunspots were supposed visible without magnification using eclipse glasses.
I tried and didn’t see anything.
I couldn’t see it either, but didn’t have my glasses with me. My wife and daughter could see the big spot behind these CMEs immediately.
