The RATAN-600 observations of solar active regions:

• experimental evidence was found of the existence of cyclotron emission lines, earlier predicted by Zheleznyakov V.V. and Zlotnik E.Y.; the line detected was located in a bright source of thermal nature and had an emission band of 10-12% at the wavelength of 8.5cm, the brightness temperature of 10⁷ K;
  (Collaboration with the IAP RAS).
• direct measurements of the magnetic field in the coronal hole at the bottom of the corona were performed, the magnetic field strength (the calculations were carried out as part of the thermal bremsstrahlung mechanism of radio emission generation of the solar plasma in the weak magnetic field) increases from the values of 0.2G at the photosphere level up to 7-10G at the level of radio emission formation at the wavelength of 18cm and is then remains unchanged (or decreases slightly) down to the level of radio emission formation at the wavelength of 30cm.
