If my memory serves me correctly, there are HAARPs or their equivalent in Alaska, Norway, Russia, China, and Australia. Alaska's is at Poker Flats. China's is close to the Mongolian border. If they heat up the ionosphere at night, people in a wide area can see something like the picture I posted above. Because it is secret, and not publicly discussed, I can only conclude that this technology is being weaponized. What the world really needs in this area is a knowledgeable whistleblower.
