Getting hit with a CME has happened and will happen again.
But...and this what everyone should remember:
The CME has to be large, AND directed at where the earth is going to be in a couple of days when the particles actually hit us.
So...think of hitting as cue ball, flying through space at 20,000 miles per hour...with a shot gun from 93 million miles away.
Not “impossible”—because its happened before. But listen to your local HAM operators because they will know when it is going to happen.
Have you seen the Nicolas cage film Knowing?.......
Yep, check out the solar flare in 1859. Melted telegraph wires. Imagine the damage it would do today.
