It missed us by 9 days

This was fantastic but you left out the word "inevitable" .. this isn't an IF it hits us It's WHEN it hits us... and the potential of North American or European mass grid failure is horrifying prospect.. essentially back to dark ages,  no modern medicine .. limited surgical procedures... complete overhaul of all labor,  transportation dead in water literally.. no sewage treatment,  no water pump to homes unless you're on mechanical well.. it's the single most devastating disaster if our Star decides to throw a fit..
