(Astrophys. Letters). The type V burst has been defined as a wideband continuum which sometimes appears for a minute or so following a type III burst (Wild et al., 1959b). It is now generally accepted that type III bursts arise from plasma waves set up by electrons escaping with velocity ~c/3 along open magnetic field lines (Wild et al., 1959a; Stewart, 1965); the most widely accepted explanation of type V continua is that they arise from plasma waves set up by electrons of similar velocity which have become trapped in a coronal magnetic loop (Weiss and Stewart, 1975). On this hypothesis the plasma waves are set up by two opposing electron streams in the trapping region, and from this consideration Zheleznyakov and Zaitsev (1968) have concluded that type V emission should be predominantly at the second harmonic of the local plasma frequency. In this paper we describe and discuss some two-dimensional observations of source positions of type III–V events which were obtained at 80 MHz on the Culgoora radioheliograph.
