Bestimmungen der Radioelemente i und OMEGA der Sonne.
Abstract
A description is presented concerning the approaches used for the determination of the position of the solar axis in space. This position is defined by means of the inclination of the axis relative to the perpendicular on the ecliptic (i) and the angle between the point of intersection of the solar equatorial plane with the ecliptic and the vernal equinox (Omega). Historical developments related to the study of seasonal changes of the orbital forms of sunspots during their east-west motion over the solar disk are considered and details are provided regarding the determination of the solar rotational elements on the basis of the Doppler velocity measurements of the solar plasma. The significance of these measurements for current solar studies is also discussed.
