Discreteness of the rotation periods of the solar and interplanetary magnetic fields (in Russian)
The rotation of solar magnetic fields during 1954-1980 has been investigated using data sets for the polarity of the interplanetary magnetic field (IMF) and measurements of the mean magnetic field of the sun for 1968-1980. Each data set used in the analysis was treated as a single time series. The power spectra of the fields show a set of discrete peaks near the solar rotation period of 27-28 days. The most significant peaks were well reproduced in both the IMF and SMMF spectra. It is shown that neither sampling effects nor the interference of the 27-28-day variations in the long-term evolution of the IMF and SMMF can account for the concentration of power in the discrete lines. The solar magnetic fields at high latitudes (40-50 deg) appear to contribute significantly to the SMMF as measured by a solar magnetograph, and to the IMF observed at earth orbit. 27 references.
