DESCRIPTION:Speakers: Dr. DRESCHHOFF\, Gisela (University of Kansas)\nAn a
 nalysis of the solar magnetic field strength (B(nT)) was based on the \nte
 mporal evolution of the minimum (Bmin) values in relation to the maximum \
 n(Bmax) values of the 300-year data series.  Three results seem of particu
 lar \nsignificance.  A two-step cycling mode is exhibited by the absolute 
 values of \nBmax and Bmin.  The ratios of Br = (Bmax-Bmin)/(Bmax+Bmin) can
  be defined as \nthe dimensionless quantity of ?visibility?\, which\, when
  approaching zero\, would \nhave profound implications for the occurrence 
 of deep minima.  A third result \nseemed to indicate that there are optimu
 m conditions within the energy \ngenerating region of the Sun to result in
  the observed Schwabe cycle of ~11 \nyears.  This highly speculative inter
 pretation is based on the varying \ncontributions from either predominantl
 y hydrogen (H-1) or helium (He-3) \nburning in the core. Here it is furthe
 r speculated that the core contributions can \nbe extended to the fundamen
 tal solar Hallstatt cycle of ~2200 years displayed \nin the Holocene radio
 carbon record.  The temporal evolution of the Hallstatt \ncycle will be di
 scussed making use of the simple concept of ?visibility? to \ndescribe amp
 litude and frequency modulation of the Hallstatt cycle.\n\nhttps://indico.
