A possible relationship between spectral bands in sunspot number and the space-time organization of our planetary system

  • H. Schwentek

For the particular purpose of this paper, Zürich relative sunspot numbers of the time spans 1749–1982, 1749–1865, and 1866–1982, have been analysed anew by two different methos. It is shown that the spectral bands in the power spectra of sunspot numbers between 1 and 234 years obtained from these analyses can be clearly related to the modified configuration frequencies of the giant planets and their harmonics. In particular, the clearly dominant spectral band in sunspot number, the solar cycle of 10.8 years, is given by the configuration period of Jupiter and Saturn (19.859 yr) times the ratio of their distances from the Sun (0.545).
