The K-index for this is an 8 which is one less than an extreme G5 geomagnetic storm ( https://en.wikipedia.org/wiki/K-index ). I haven't been able to find it, so I'm curious what the Carrington event K-index was?
SWPC is now showing this storm as a G5 with a K-index of 9: https://www.swpc.noaa.gov/

If you really want to be safe: put it in a cardboard box, wrap the cardboard box in air tight aluminum foil or a metal container, and then put the whole thing in another cardboard box to prevent any grounds or shorts.
That seems pretty excessive, IIRC if there's not a really long linear length of wire involved (e.g. power lines) then things are probably fine.
PJM (the US east coast power grid) has issued a warning: 104202 Warning Geomagnetic Disturbance Warning 05.10.2024 13:48 PJM-RTO A Geomagnetic Disturbance Warning has been issued for 13:48 on 05.10.2024 through 21:00 on 05.10.2024. A GMD warning of K8 or greater is in effect for this period. Times are US EDT. This is a warning only. No actions are listed yet.

Because citizens aren't expected to need to know the scale. They are only expected to follow the guidance their governments issue.
I like the response, seems very astute of an observation. Interpreting this in the worse light possible… in other words, gate keeping. I think a lot more people could understand and be mature in a lot more things if artificial and archaic barriers weren’t erected. I think not trusting the public is a recipe for an obscure elite ruling class. Sure, not a whole lot of people will get it but at least be open about it. T…

PJM is still at "warning". No alerts or actions are listed. If problems were expected, there would be alerts and preparatory actions. PJM mentions that they turn off guest access if the site overloads. So please don't over-use this link.
Minor update: the warning has been extended another 16 hours, but downgraded from K8 to K7.
' A Geomagnetic Disturbance Action has been issued as of 22:15 on 05.10.2024 to protect the power system from damage or disruptions due to increased geomagnetic activity.'
Is there any danger of people flying in planes during this time? Will there be any radiation exposure?
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.
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.

Humanity is good in sweeping problems under the rug and not preparing to various threats.

Also a small camping stove with a couple of gas cartridges to ensure you can cook your rice and pasta.
Keep some oats, you can eat them raw.
It should be noted for other readers, that it’s processed oats that have been treated with steaming and an extended heat treatment that are safe to eat as is. That said, “overnight oatmeal” is still not recommended.
The steaming and heating steps allow oats to be shaped, modifies the flavor, kills the many possible pathogens present (like ecoli and salmonella) and deactivates enzymes that would cause spoilage.
Truly raw grains should not be eaten. For example in the US the biggest danger of food poisoning from eating raw cookie dough, typically comes from the flour not the eggs. Incidentally, simply baking flour does not render it safe until moisture is added: https://ag.purdue.edu/news/2021/04/Home-kitchen-heat-treated...
I should also add that things like dry kidney beans contain toxins that need to be soaked and heated to boiling for a sufficient amount of time to destroy, otherwise even just a few can cause severe intestinal distress.

That seems pretty excessive, IIRC if there's not a really long linear length of wire involved (e.g. power lines) then things are probably fine.
Why would long lengths of coiled wire not be affected?
To induce an appreciable current, the magnetic field has to act on a wave-compatible portion of the conductor. The length and alignment of the wire has to resonate with the direction and length of the wave.
