摘要: In this study we continue our investigation of the radio sources located above neutral line radial magnetic field in solar active regions, i.e., so-called associated (NLS). The nature NLS is still far from being understood. To it, use spectroscopic capabilities new broadband polarimetric facility RATAN-600 telescope. We spectra several regions over a wide range variations their sizes. find emission fluxes to be related gradient quasi-longitudinal photosphere. estimate vertical positions relative cyclotron sources. fine spectral features emission, which confirm presence current sheet associate appreciable lack polarization such with location near tops coronal arches.
