From investigating spectrograms of penumbrae of some sunspots it is concluded that the maximum magnetic field strength occurs in dark filaments and amounts to 1800-1900 G; the intensity of the magnetic field in dark filaments is 100-400 G larger than in the neighbouring bright filaments; the bright

This paper deals with the conception that two-dimensional turbulence is present in a sunspot where the magnetic field is strong. This conception is based upon the incapacity of even a strong magnetic field to influence an arbitrary two-dimensional turbulence, if the magnetic field is parallel to a c
We obtained simultaneous spectra with a spatial resolution of 89 and a temporal resolution of 15 s in Hc~, Can-K, Car1 8542 A, and three FeI lines of the sunspot group responsible for the large flares of August, 1972 (McMath No. 11976). A time series taken 1972, August 3 in the Fe16173 A. Zeeman sen
The potential models of the unipolar sunspot magnetic field are calculated on the basis of magnetographic measurements of the magnetic field made in the three spectral lines of different intensities, H c~, Ca 1 26103 and Fe 1 2 4808. The computed distributions of the magnetic field vector are compar
