Description
Summary:From 1968 to 2017, the Crimean Astrophysical Observatory, the Wilcox Solar Observatory, and five other observatories performed more than 27 thousand daily measurements of the mean magnetic field of the Sun‐as‐a‐star. These data reveal the presence of the long‐term coherent periodicity PS = 13.4582(25) days, characterizing the four‐sector pattern of the magnetic Sun. To clear up the origin of this periodicity, motions of planets and massive satellites are considered in detail. It is shown that the best commensurate timescale of all those periodic motions is equal to PG = 13.4577(10) days, which agrees fairly well with PS (the probability of a chance coincidence is less than 2 × 10−9). Physical nature of this odd PS–PG resonance is unknown, but it is supposed that the phenomenon is caused by coherent periodic fluctuations of the gravity field within the solar system.
