AbstractA large set of observations of the Sun at 37 GHz is analysed. An association of 99% is found between the regions of brightness temperature depression and the magnetic field inversion lines. Observations indicate a possible existence of "giant cells" with duration of 1-2 years and a longitudinal extension up to 90°.
