Solar service KRIM in the radio range
Four automated radio telescopes of CrAO integrated into the Solar Service KRIM perform solar observations in the monitoring and alert modes. The RT-22 radio telescope is equipped with polarimeters at wavelengths 0.8, 2.0, 2.3, 2.8 and 3.5 cm, which allow recording the intensity and circular polarization of radio emission. The directivity diagrams at the mentioned waves are 2.5–6.0′. The RT-22 radio telescope receives emission at centimeter wavelengths to gain knowledge about processes in the lower chromosphere. The RT-3 receives emission at decimeter wavelengths to derive data about processes in the upper chromosphere and lower corona. The RT-M receives emission at meter wavelengths to detect corpuscular fluxes directed to the Earth due to solar flares. Simultaneous observations at four telescopes which cover the wavelength range from 8 mm to 1.2 m allow us to acquire information for analyzing energy release processes in the solar atmosphere and making short-term prediction of solar activity. Data on the radio monitoring of solar activity are maintained in real time in a digital format and presented on websites of the International Solar Service, which involves 14 ground-based stations in cooperation with orbital observatories.
