4. Structures inside coronal holes, distribution of plasma parameters in holes with the height.
     5. Bright coronal points - local energy release in the corona. They are observed at the SSRT and NRH simultaneously. The brightness temperature ratio is indicative of the bremsstrahlung mechanism of emission. Nevertheless, two frequencies are insufficient for identifying the plasma parameters.
     6. Applications. Short-term prediction of geoeffective solar flares, base don a number of signatures (polarization structure depending on the structure of the photospheric magnetic field and on the active region location on the solar disk, evolution of the microwave emission flux, etc.). Recording of CMEs. Diagnostics of solar flare parameters. Alerts within the space weather program. Education of young scientists with the new instrument.
     The solution of the above-mentioned problems substantially alters and enhance the requirements for new solar radio telescopes.  The MWRH project provides for the attainment of a time resolution on the order of 1 s, and the sensitivity and dynamic range will be sufficient for recording all forms of solar activity, the angular resolution can be improved using remote antennas (such as the antenna 32 m in diameter that is already under construction near the SSRT for the Russian RSDB “Quasar” system).
