It missed us by 9 days

Two problems:
1. You said that CMEs don't effect our bodies.  
But, SuspiciousObservers found several articles on how changes to the solar magnetic fields bothers animals and humans.

2. Are we ready for a CME?  
I hope so.  President Trump ordered the electric grid operators to harden their equipment that serves critical infrastructure, such as military bases.  It is not too hard to do: add dc current sensors (Hall Effect transducers) and protective relay logic that is looking for a quasi-dc ground current.  If the summation of dc current pulses lasts longer than 1 minute, trip the breakers or switches that normally connects this transformer to the grid.  Backup protection option:  put temperature sensors on the magnetic core and transformer frame.  If either gets too hot, trip the breaker or switch.  
Leave the breaker tripped for at least 10 minutes, then evaluate whether it is safe to close.
Why trip the breaker?  The quasi dc causes overheating, which damages the insulation, resulting in a short circuit, causing a fire.  The transformers that are high priority for this protection are huge.  The waiting list for building one of these is NORMALLY 9 months or more.  If we have many of these transformers fail at the same time, then WOW!!!  How long will it take to build just the biggest, most important transformers?   Shutting down the grid for 10 minutes is not as disruptive as 9+++ months.
