Why were monopoles raining? I just watched Robotics;Notes. The manga not yet.

A monopole fell from the sky. And later, lots more begun raining.

It was a recurring theme in the series that there was a solar flare cooking up, so I was under the impression that it was also making funny things in the earth's atmosphere kinda explaining the monopoles.

But later in the series we find out that


   There is no solar flare at all. All the info about it is fake.


So, what's up with the monopoles?

My next guess was that it was part of


   Kimijima Kou's plan to make the whole solar flare thing more realistic by somehow synthesising monopoles and throwing them off the sky (somehow)


But I'm not sure if that's confirmed in the series or the manga.
As explained by Reading Steiner in this question on ask.fm, this isn't actually covered in the anime, but in the VN, Kai knocked the HAARP Radar into the sweet spot for electromagnetic interference, creating them.
