Is there any danger of people flying in planes during this time? Will there be any radiation exposure?

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.
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.)
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.

I've got an assortment of backpacking/camping water filters, but don't live especially near a water source, so my days would revolve around walks to the nearest creek. (2 km away) A cargo bike would help a lot there. If the municipal water is still functional but non-potable, a LifeStraw Max gets you effectively unlimited water on-demand for most sources of contamination.
You could collect rainwater, but realistically water outages are usually not "the taps are dry", but rather "the water treatment plant failed so we can't guarantee the water is safe to drink."
Consider: "The pumps aren't working and there's nothing left up inside the local water-tower."
Then you'd have to travel to get any appreciable amount of water before even starting to filter it.

Best way to prep is strong community connections around you. Community is resiliency.
LOL we saw how that played out with COVID. 1/2 your "community" is going to deny the disaster and deliberately worsen it. 1/2 (with some overlap) is going to go from grocery store to grocery store buying all the necessities to resell them later. EDIT: Wow, I know HN wears rose-colored glasses when looking at the past, but come on, people. We didn't hallucinate the antimaskers, antivaxxers, and thousands of protestors…
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 f…

Fascinating, if anyone has info on other grids that share these types of alerts, pease link!
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.

The genius move I heard of was to throw a few 5-gal jugs of water up in your attic (!!!). It's relatively shelf-stable, standardized size, and "in case of emergency" you can even use it as a gravity-flowed spout to fill smaller containers below. I've taken to trying to have a minimal set of 4 one liter steel water bottles hung in the closet (grab + go) all the time. So convenient to be able to "just grab some water"…
If it's kept in plastic containers, it's probably only good for a year or so before enough stuff leaches into the water that it'll last off and funky. The time period decreases significantly if your attic gets hot (like a lot of them do).
