✦ Synopsis

This paper presents some results of observations of the mean magnetic field of the Sun as a star (SMMF) at the Sayan Observatory during 1982-1984. A description of the instrument is given, as well as some major points in the technique of data acquisition and treatment such as calibration, zero-level control, etc. The comparison of a new SMMF series with observations from the Wilcox Solar Observatory showed a high correlation between the two series (p = 0.88) but with a rather great difference in amplitudes. We discuss time variations of SMMF, both long-term caused by the magnetic field evolution with the activity cycle and those of shorter time-scales caused by solar rotation.
