[PEM12-P21] Long-term variation of Schumann resonance parameters at Kuju station
Keywords:Schumann resonance, solar activity
The ground magnetic field variation in the extremely low frequency (ELF) range has been measured by an induction magnetometer at KUJ since 2003. The observation is a part of activities by International Center for Space Weather Science and Education Kyushu University.
The fundamental mode of the Schumann resonance (SR1) around 8 Hz can be seen at KUJ. The peak frequency of SR1 correlates with F10.7. Also the correlation between SR1 amplitude and F10.7 reveals. The SR parameters seem to be affected by the ionospheric conditions which change depending on solar activity.
