You're not alone. Unplug things? Plan on the power being out? That New Yorker story I mentioned above is called "Starburst". If we get a top end G5/Carrington event, no one seems to know how to prepare for that level solar storm or what it will do because we haven't had one in a hundred years. It suggested the possibility of the grid being down, worst case, for 2+ years (transformers are mostly custom built and not in the USA).
