... Three day radio-astronomical forecast of the proton activity of the Sun: The figure shows multiwave radio emission scans - graphs of the distribution of intensity I and circular polarization V across the solar disk, obtained at RATAN-600. ... According to this criterion, for a proton flare to arise, the flux of radio emission must be sufficiently high at short wavelengths (blue color scans) and should increase with time compared to the general intensity. ...
