LOW-FREQUENCY OBSERVATIONS OF DRIFTING, NON-THERMAL CONTINUUM RADIO EMISSION ASSOCIATED WITH THE SOLAR CORONAL MASS EJECTIONS

Low-frequency (80 MHz) imaging and spectral ( approximately 85-20 MHz) observations of moving type IV radio bursts associated with coronal mass ejections (CMEs) from the Sun on three different days are reported. The estimated drift speed of the bursts is in the range approximately 150-500 km s~ super(1). We find that all three bursts are most likely due to second harmonic plasma emission from the enhanced electron density in the associated white-light CMEs. The derived maximum magnetic field strength of the latter is B approximately 4 G at a radial distance of r approximately 1.6 R sub([middot in circle]).
