Abstract
Seven observatories performed in 1968–2015 numerous daily measurements of general magnetic field of the Sun seen as a star (of a mean line-of-sight field component of the visible solar hemisphere). The new data 2013–2015 confirmed the recent prediction about saw-edged profile of the mean curve of the Hale’s 22 years magnetic cycle and, thus, a hypothesis about its cosmological (partial) origin. This is supported by a special analysis of epochs of extrema of Wolf’s sunspot number, demonstrating a remarkable stability, since Galileo’s time, of the initial phase of the cycle, which can hardly be explained by dynamo theory exclusively.

We are grateful to C. Bizouard (Paris) for fruitful discussions of odd properties of the Sun and our Universe, and thank M.L. Demidov (Irkutsk), A.G. Tlatov (Pulkovo) and the WSO and NSO observers for their numerous GMF measurements, and also the referee for useful comments. The NSO data were acquired by the SOLIS instruments operated by NISP/NSO/AURA/NSF, and the present study was funded partly by RFBR according to the Russian Research Project N 16-02-00221 A.
