287. http://www.sao.ru/Doc-en/Science/results/ar_solar/d03-bogod-e.pdf
The observation of active regions with RATAN-600 and the Beijing Astronomical Observatory spectrograph in the decimeter wave band shows an existence of a long-term non-thermal emission of active regions in continual (a halo) and flaring (flares and micro flares) components. The observation-compatible models have been devised specifying the nature of continuum as a radiation originating in the non-linear interaction of plasma waves at the upper-hybrid frequency. ...

... 1994: . As a result of comparing the spectra of active solar regions from the observations with high spatial resolution in the microwave range at the RATAN-600 (the S-component) with a flare component observed at meter wavelengths on the VLA (USA) we revealed the presence of a strong and prolonged noise storm exactly where a weak decaying active region (with the presence of powerful active regions in the disk) is located. ...

... 1996: . Using the original method of diagnostics of the Solar corona structure by the effects of radio wave refraction (space-frequency tomography) in the wavelength range of 2-30 cm on the RATAN-600 telescope, the electron density, emission measure and porosity of coronal loops was measured for the first time regardless of the optical data. It is shown that most of the matter is concentrated in the super-dense loops, occupying less than 10% of the total coronal volume. ... Archive . ...
