Audent writes "Otago University researchers are concerned by U.S. plans to protect satellites from solar storms... "The approach, which is being considered by the U.S. Air Force and the U.S. Defense Advanced Research Projects Agency, involves using very low frequency radio waves to flush particles from belts and dump them into the upper atmosphere over either one or several days". The plan could disrupt GPS signals and high frequency radio over the Pacific for up to a week. "The disruptions result from a deluge of dumped charged particles temporarily changing the ionosphere from a "mirror" that bounces high frequency radio waves around the planet to a "sponge" that soaks them up.""
