    we would have 10 minutes or so of time to prepare

    More like a couple of days. Coronal mass ejections (which is what the Carrington event was) can be seen leaving the sun, there’s good software to track and predict their trajectories and how much they dissipate (or don’t) en route.

    No CME has an arrival time on the order of 10 mnutes.

    Solar flares, on the other hand, are very near light speed. By the time you see one, it’s already hit you.
