I am not an expert, but it’s worth noting that the kp index has a maximum value of 9. So though the Carrington event had a kp of 9, its intensity on the related (but not capped) HP30/HP60 scale [1] would likely have been higher. [1] https://kp.gfz.de/en/hp30-hp60
Queue Chernobyl documentary clip measuring the radiation as low because that’s as high the meter went
If anyone is interested in what "G4" means in context, here's the scale: https://www.swpc.noaa.gov/noaa-scales-explanation
Anyone have a sense of magnitude for this advisory? How much more radiation should an airline passenger expect to receive during a G4 event than normal?

With how much modern cars rely on electronics, I would not try to drive during such an event.
No one would drive to the pub anyway. Better walking back home…

We are at kp 8.67. The Carrington event was a kp 9
I don't ever recall seeing these in the news so frequently. It feels like there are several a year now. A decade ago, never.
And I also never remember seeing Aurora at my latitudes.
Do we just have better sensing now, or is there some cycle on a period longer than a few years? Or maybe I'm crazy and just never noticed.

Have we been having these more recently? I don't ever recall seeing these in the news so frequently. It feels like there are several a year now. A decade ago, never.

What if one of my homelabs needed 100% uptime to meet my wife's SLA for messaging? Is this able to be protected?

G4: " Induced pipeline currents affect preventive measures, HF radio propagation sporadic..." G5: " Pipeline currents can reach hundreds of amps, HF (high frequency) radio propagation may be impossible in many areas for one to two days..."
Looks like G5 is the highest level and the scale system is used by NOAA.
