... 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. ...

... We publish 16 Doppler imaging temperature maps for the years 1994-2002 of the active RS CVn star II Peg. ... Through Doppler imaging we want to study the spot evolution of the star and in particular compare this with previous results showing a cyclic spot behaviour and persistent active longitudes. ... The derived temperature maps are quite similar to the ones obtained earlier with a different methods, the main differences occurring in the spot latitudes and relative strength of the spot structures....
