Answer to Question #27403 in Atomic and Nuclear Physics for mike schlack

Question

Can you tell me what causes a rare Broadband Low Frequency signal that Fluctuates, sometimes rappidly, sometimes slowly, but rare? Is it a Geomagnetic pulse or X-rays or Gamma-rays from the Sun? I cannot pinpoint the correct graph to watch. It carries a 5KHz signal with it, if that helps. Thanks, mike
