www.spaceweather.gov/CME about to hit earth. Not measured as big, but may cause some damage. I am surprised there isnt more traction with this... its kind of a big deal (maybe not so much in outcome), but I only see anything about this on clickbait sites. I put on my tinfoil hat with things like this and assume that to avoid a panic, its deliberately down played. being in winter we are protected against this to some degree which is good, sorry to the northern hemisphere folk. One day a big one will get us. who knows what happens then, but ive consumed so many grid down books that I only see one outcome.

It wil, be a reality one day, but a nuke emp is more likely in my muddy crystal ball. |

yeah, on a long enough timespan they are both inevitable. I just dont see a nuke emp without nuke strikes, and we dont know how that will actually look.
I would also imagine a big cme will prompt nuclear strikes too. Who knows what else governments will do.
besides the personal prepping, a grid down scenario is what I keep in mind

Haven't really looked into this topic before so I hope you can confirm if I'm correctly working out the position on Earth where the CME hits and is most intense. ie: At its maximum over the Pacific at approx 2022-07-19 22:55 UTC (give or take a bit due to my pausing the video prior to the screen capture)  And from what I could digest from the website it doesn't look particularly worrisome even if it were directly over heavily populated areas. Would I be right in my assessment? |

I am no where near knowledgeable in this area, but to me its kinda like someone having a misfire while you're in the sights. it could've been it, and we should consider ourselves lucky that it didnt go another way. We should be doing everything to protect ourselves for next time.

Due to seeing how often they occur but miss us, we have a good estimate of the probability of a carrington event repeat. It's roughly 1% per year.
What we don't know is how often a really big one lets go. A 'melt everything that conducts electricity' style event. For that we'd either need to have millions of years of observations, or close up monitoring of a huge number of similar stars elsewhere in the galaxy. We have neither.

Be prepared, aerials for the radios always earthed and disconnected, except when actually using them, wiring from and to the solar systems in steel pipe and underground, solidly earthed, battery's always referenced to a solid earth as well, spare computers for the vehicles wrapped up under the seat in a tin box, with tools to change it out.
Spare equipment, inverters, comms gear and so on, in a steel shipping container, insulated from its walls, but also with a high impedance leakage path to earth to drain any excess charge, without causing a current spike to damage anything, basic static or lightning protection precautions.
We should have adequate warning that one is headed our way, but given how badly our Govts have behaved, especially in relation to the Jabs, do you really think they will let us know of an event heading our way ? But you can be sure the various Military's are taking the threat very seriously.
In any case, we in Australia should be prepared for severe electrical storms, and protection from them is like protection from an EMP, except the EMP is 'faster' electrically, and potentially lasts longer, meaning more energy to dissipate. Mov's are available to cope with such pulses at a price.

And don't forget to keep a spare microwave for anything that needs serious protection. They make great faraday cages.
If planned for, Australia can largely survive a CME due to our latitude if prepared for it (we are not prepared for it.
In a nutshell, Canada, Norway etc are in big trouble. The more equatorial regions are better protected by the magnetosphere. The polar regions are where the flux lines cross through the crust, concentrating the damage. Be a hell of an aurora to see though.
