It missed us by 9 days

@Physics Girl: We don't need to "boost" our infrastructure. Maybe "insulate"? So everything doesn't catch on fire. I don't think you very specifically described the qualities of the potential widespread damage of these electrical potential swells. Couldn't one of these cover 1̶/̶2̶ ̶o̶f̶ the whole planet at once? If it is 1000x the energy of the normal sun it would burn everything in it's path. humans alive etc. we would need to get many feet underground while it passed or we could be boiled. microwave style. We don't need to "boost" our infrastructure -outrageous! we would benefit from completely abstaining from pushing so many electrons into the atmosphere. all electronics! i wonder if all the charged metal particles all over the world being sprayed into the atmosphere could have any influence into this?...no way, right? -hmm a metallic mist...over the whole planet?(why again?) i wonder if that would attract a solar flare or CME... how many people could die? are the electrical conveniences worth our very lives?
