DESCRIPTION:Speakers: Vitaly Ishkov (leading scientific research)\nThe sta
 tistics of reliable solar cycles (SC) leads to the scenario of the regular
  changes in generation regime of the magnetic field in the solar convectio
 n zone from the epoch of ''increased'' ($) solar activity (SA) and vice ve
 rsa – from the epoch of ''lowered'' to the epoch of ''increased'' SA. Th
 ese epochs significantly differ from each other in parameters\, evolution 
 characteristics and manifestations of sunspot-forming activity. From the c
 urrent 24 SC\, the Sun entered into second epoch of ''lowered'' SA\, which
 \, taking into account the steady nature of a sunspot reliable series\, mu
 st be prolonged 5 solar cycles ($\\sim$55 of years). The consequence of th
 e low values of the background solar magnetic field became the significant
  drop the value of interplanetary magnetic field\, which in turn led to th
 e significant increase (approximately on 20%) the fluxes of galactic cosmi
 c rays in the internal heliosphere in comparison with the epoch of "increa
 sed" SA  (1944-1996). It is important to note that in the ''lowered'' SA e
 pochs there are not observed high solar cycles and in the ''increased'' SA
  epochs are forbidden the low solar cycles. In the current 24 SC the pictu
 re of solar proton activity principally changed: significantly reduce the 
 amount of solar proton events in the whole energy range\, including GLE- e
 vents and there were no events with extreme proton flux (104 pfu). This fa
 cts shows that in the first half of the 21st century\, we will have a high
  background of galactic cosmic rays\, while the fluxes of solar protons an
 d their number will be significantly less. It follows that manned space fl
 ights in the free space will become very problematic and probably should b
 e postponed for the second half of the 21st century.\n\nhttps://indico.par
