The buried lede here is we need to think harder about preparing for another solar event like happened in 993 that left its mark in the tree rings, because such events are not all that rare and the next one will destroy GPS and much of the power grid.https://www.nytimes.com/2021/10/20/science/vikings-newfoundland-age.html …

Another solar event about 200 years earlier was nearly twice as intense. And for the less intense ones (that would still fry our infrastructure) we're basically dependent on some monk somewhere writing down how weird it is that he can read by aurora lighthttps://en.wikipedia.org/wiki/774%E2%80%93775_carbon-14_spike …

Everyone loves the Carrington Event, the well-documented solar storm in 1859 that has been the gold standard for "if this happened today, we'd be toast". But the 774 event was at least 10 times as strong. The Sun does not play.https://en.wikipedia.org/wiki/Carrington_Event …

Replying to @Pinboard
Finland has more prep than most countries for solar storm effects (e.g. mentioned in 2015 national risk assessment), but unclear if any amount of preparation helps if/when an event of that magnitude occurs.
