Scientific paper

Imaging observations of a slowly moving type IV burst associated with a filament eruption are reported. This event was preceded by weak type III burst activity and was accompanied by a quasi-stationary continuum that persisted for several hours. The starting times and speeds of moving type IV burst and the erupting filament are nearly the same, implying a close physical relation between the two. The moving type IV burst is interpreted as gyrosynchrotron emission from a plasmoid containing a magnetic field of 1-2 G and nonthermal electrons of density (0.1-1) x 10 to the 6th/cu cm with a relatively low average energy of about 50 keV.
