Not even that interesting. We’ve had quite a few X-class flares without most of us even knowing it.
A CME from an X17.2-class flare hit us on 28 October 2003. And as you can see, the human race is extinct. The earth is a barren rock with no atmosphere.

It was fun getting pictures of the Aurora back then.
