Shiva Star was also used to develop an experimental weapon for the SDI effort between 1989 and 1995. The idea appears to have been to create "compact toroids" of high-density plasma that would be ejected from the device using a massive magnetic pulse.[2] The plasma projectiles would be shot at a speed expected to be 3000 km/s in 1995 and 10,000 km/s (3% of the speed of light) by 2000. A shot has the energy of 5 pounds of TNT exploding; although it caused little or no physical damage, the energy would shower the interior of the target with high-energy x-rays that would potentially destroy the electronics inside. The tests cost a few million dollars a year.[3] The project was scrapped at some time after 1995 because of problems keeping the plasma projectiles stable for the distances required by orbital weaponry.
Scrapped, Or went deep black. Nick Cook came to the same conclusion. Maybe these arte further tests, if they are unstable and dissipate somewhat at distance, that could account for the light shows.
Dont know if I really believe that or not though cos our EM shield and atmoshphere filters out radiation a lot more potent than anything we can create artificially, without any lights. plus why would it only be visible at the upper northern hemisphere?
Auroras are produced by the collision of charged particles from Earth's magnetosphere, mostly electrons but also protons and heavier particles, with atoms and molecules of Earth's upper atmosphere
