| Zusammenfassung |
| ULF/ELF magnetic field data recorded at the "Hylaty" station in
Poland (49°19' N, 22°56' E; L≃2)
are analysed to find the characteristics of spectral resonance
structures (SRS) in the frequency range 1–5 Hz, related to
the ionospheric Alfvén resonator (IAR). An automatic procedure is
employed to SRS events observed at "Hylaty" during the nighttime
in 2001–2003, to calculate the parameter which determines the separation
between the harmonics of the resonator, termed the frequency scale.
Diurnal and seasonal variations of the frequency scale within the
range of 0.4–0.8 Hz have been found. The usefulness and
disadvantages of this particular method of SRS analysis, and of
other methods, are discussed. |
