Polar magnetic flux on the Sun in 1996-2003 from SOHO/MDI data

摘要: Polarity of the polar magnetic fields on Sun changes in every 11-year sunspot cycle, affecting large-scale structure corona and heliosphere. Using SOHO/MDI data, flux radial component field is estimated for different latitudinal zones. It that total Northern zone, from $78^{\circ}$ to $88^{\circ}$, about $1.5{-}1.7 \times 10^{22}$ Mx, it $2.3{-}2.5\times Mx similar Southern zone. The new data reveal an interesting result fluxes do not vary significantly during reversals both hemispheres, while positive negative parts change.
