Implications!

- Power systems: Possible widespread voltage control problems and some protective systems will mistakenly trip out key assets from the grid.

- Spacecraft operations: May experience surface charging and tracking problems, corrections may be needed for orientation problems.

- Other systems: Induced pipeline currents affect preventive measures, HF radio propagation sporadic, satellite navigation degraded for hours, low-frequency radio navigation disrupted, and aurora has been seen as low as Alabama and northern California (typically 45° geomagnetic lat.).

The sky is falling! Seriously, though, I am not knowledgeable enough about these CMEs and how they compare to the past ones. Are there any good historical analyses?

Not saying anything about the current storm, but a storm as strong as the Carrington Event[1] would make modern day life on Earth pretty unpleasant. Some of the potential impacts are documented in Severe Space Weather Events: Understanding Societal and Economic Impacts [2]

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.

Or load on ammunition, and be ready for your neighbor to go cannibalistic within 3 months...

Ignoring unrealistic preparations for most of us (such as bunkers and whatever else), an adequate supply of food and water to handle disruptions to logistics for a realistic amount of time must surely be the lowest hanging fruit (e.g. a month?). This is fairly trivial if you aim for things like rice and pasta, and if the grid goes down for longer than a month a lot of us are dying regardless of how we prepare.

If you are in the US, the best preparation you can have is to be able to relocate during an emergency. Do not get stuck in Katrina so to speak. Having transport to other parts of the country is the best bet.

One less obvious CME prep suggestion that I have heard is to prepare for extensive forest fires.

* Have a well stocked pantry. Costco business centers sell large bags of rice, beans, etc. very cheap. It just doesn't hurt to have some of these things on hand and use them.

* Have solar installed on your home. Have some spare disconnected inverters, maybe even a couple of uninstalled panels.

* Grow some of your own food in a garden.

* Have good relationships with some of your neighbors.

* Know how to do stuff yourself, have some tools and building materials in your garage

* Have a bicycle

* Have a method to purify water

None of these things are bad ideas anyway. Just don't be absolutely reliant on just-in-time purchasing of life necessities and know enough to be able to figure stuff out on your own. More or less just go on an overnight backpacking trip once in a while without buying prepackaged everything and you'll be pretty good.

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.

The water seems like the hard part. Are there any tricks for cheap, safe hydration for a family?

I guess we could just start building walls of unopened water bottles in our basement…

(In my teens I saw a family friend had a bag full of food supplies. I asked someone if that was a prep bag, and they said yes. I thought they were a bit weird. Now I’ve come full circle browsing Amazon for cheap doomsday food.)
