No, CME's were NOT discovered by spacecraft in the early 70s, this was
the first direct observation of a CME as it happend.

The first CME noted was the massive storm of 1 September 1859 but it required
the discovery of X-rays and the recognition of the ionosphere before it
could be understood what happened.
