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

β¦ 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.

An analysis of relationships between latitudinal fine structures of the photospheric plasma differential rotation and solar activity shows that sunspot activity seems to be lower (as measured by the number and extension of sunspot groups) at latitudes where minima of angular velocity appear. ## I.
Frazier (1972) has criticized the conclusions of Zirin (1971Zirin ( , 1972)), Veeder and Zirin (1970), and those of Foukal (1971a, b, c) on the relation between He structure and magnetic fields. We wish to reply to these criticisms. Some of the points Frazier mentions refer to statements made by
A statistical mechanics of the velocity and magnetic fields is formulated for an active region plasma. The plasma subjected to the conservation laws emerges in a most probable state which is described by an equilibrium distribution function containing a lagrange multiplier for every invariant of the
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
