✦ Synopsis


Abslract. We have conlpiled the resuhs of our long-term studies of the local magnetic lield and ils activily development, derived from investigating stlnspo[ group evolulion, photoelectrically measured Iongiludinal magnetic and velocity fields, and measurements o[ stmspot proper motions. We estimate certain reguh.lrities according Io which the magnetic and velocity fields, and photospheric, as well as chromospheric activilies develop. Wc speculate about the p[Lvsical background of such processes.

By means of a device described elsewhere (BECKERS and SCHROTER, 1968) we obtained spectra of the quiescent photosphere in the Fe line 2 6173 A (9 =2.5) simultaneously in the two opposite circular polarizations. Two sets of spectra with good spatial resolution were selected to measure and to correlat

Average (over longitude and time) photospheric magnetic field components are derived from 3' Stanford magnetograms made near the solar minimum of cycle 21. The average magnetograph signal is found to behave as the projection of a vector for measurements made across the disk. The poloidal field exhib
