Abstract
The properties of moving type IV solar radio outbursts observed with the Culgoora radioheliograph and radiospectrograph suggest that these outbursts - even those which rise to great coronal heights - originate through Langmuir-wave conversion. This implies that coronal densities are sometimes greatly enhanced.
