Interestingly enough, solar scientists didn't even know there was any
such thing as a CME until the first sun-watching satellites were
launched in 1970 (I think). Cycle 20, which peaked around 1969, was a
fairly weak one. I'll bet the Apollo astronauts are glad of that.
Walking on the surface of the moon is not a good place to be if a
sunspot decides to get nasty.
