Fig. 1. Above: temporal course of fluctuations parameter for 43 years, about 19722014. Below: the amplitudetimefrequency diagram of 11years variation evolution for the investigated period. On the right: global spectrum, as a whole. Below  bending around amplitudes of variations. The locality of 11years variation on the diagram is shown by a horizontal arrow at the left. The vertical arrow is indicated of the beginning of lowfrequency drift of 23 cycle period. Conditionally, are shown the periods change sign of general magnetic field Sun and, accordingly, numbers cycles. annual values of cosmic ray fluctuations parameter in relative units. The periods of change of a sign on a field are conditionally shown. In an average part of figure, on the diagram  evolution of the period 11years cycles in time. The location of 11years variation is noted by a horizontal arrow at the left. The beginning lowfrequency DRIFT of the 23 cycle period is indicated by
