  It is shown that the description of the solar cycle that takes into account
the odd zonal harmonic of the solar magnetic field allows us to deepen our
knowledge of two important aspects of the solar activity. First, to clarify and
expand predictions of the evolution of the cyclic activity of the Sun in the
near future. Second, to develop a program for monitoring the spectrophotometric
characteristics of radiation of the solar-type stars aimed at obtaining new
information about their magnetic fields.
