I have wondered about this. From my understanding the reason main power lines etc are affected is that the long cables turn into an antenna of sorts which allows induction to occur from the CMe. So things like small electronics etc shouldn't be affected. However, that's where I wonder about the "shouldn't" part. Wouldn't a large CME like this cause excessive power surges, which modern electronics don't respond well to? i.e. nearby lightning strikes can kill a computer or microwave even if you've got a circuit breaker, so wouldn't the grid suddenly having a massive surge go through it still be a cause for concern? Or are we talking voltage/amp levels below that of a lightning strike?
