Dude in the article it says it could be "electromagnetic noise emmited from the auroras, or radiation belt."
The sun is also in a higher state of activity.. creating bigger flares from it... meaning more electromagnetic energy getting sent our way.
It could be that, and not one of those stupid a.ss "theories" you suggest.
i didn't read the article. but underground bomb testing noises are at least very similar to what people have beenhearing with this and what i heard in the vids.
HAARP does mess with all sorts of atmospheric sh*t, as a civilian we just don't know...
and somebody else, scoffing project bluebeam... really? no, it has zero to do with some french guys prediction in 2000, it's a real NASA program...
