The Type IV Solar Radio Burst at Metre Wavelengths

Abstract

Properties of 24 sources of type IV emission at metre wavelengths (including the long-lived continuum storms) have been observed by interferometry in the frequency range 40-70 Mc/s and by dynamic spectroscopy in the frequency range 15-210 Mc/s. The characteristics investigated are the positions, movements, and angular sizes of the sources, and the spectrum and polarization of the emission.
