A reality of solar global magnetic fields Stokes-meter observations with polarimetric accuracy as high as 10−5 – 10−6, and the dependence of Stokes V profiles on distribution of surface magnetic fields in the central zone of the disk are demonstrated. A possibility to use solar disk-integrated and spatially resolved magnetic fields measurements for testing of magnetic fields mapping methods on Sun-like stars is suggested.
