    Geomagnetic
          pulsation detected with induction coil, inside the red ovals.
          Schumann resonances marked in left side.

    Geomagnetic pulsation detected with induction
            coil, inside the red ovals. Schumann resonances marked in right
                  side.

          st. 01 - IK1QFK  CUMIANA (TO), NW
      Italy
     
        Despite the location of Cumiana uses the same induction coil of
        Sogliano, here the signal of geomagnetic pulsation is not
        visible: 
        it is completely covered from the signals coming from the
        railway line, passing 5 km away from the coil.
