Abstract

Properties of solar type IV radio emission consisting of a continuum and superposed fine structures are investigated. We analyze a large data set of single frequency time profiles recorded in the dm-m band by the INAF-OAT radiotelescope. It is shown that the maximum peak is proportional to the average value of the background continuum. This relationship is similar at all observing frequencies, whereas the relationship between the average background level and the burst duration seems to be frequency dependent. The existence of short type IV-like events that consist of only one “train” of periodical structures is reported.
