Meanwhile, at https://wattsupwiththat.com/2018/02/15/scientists-make-first-direct-obse… … scientists make the first direct observation of electrons creating the Northern Lights. The headline may very well be not all it is cracked up to be but the gist of the story is that they now have verifiable and incontrovertible evidence. The study is published in the journal Nature (Feb 2018). The early set of comments are interesting as they include the ruminations of solar physicist Lief Svalgard, replying to other people.
