Abstract
THE different components of the solar radio emission at metre wave-lengths were classified according to their spectral properties by Wild and McCready1 in 1950. In this classification the noise storm or type 1 radiation is characterized by a relatively steady enhancement over a wide range of frequencies, usually with short-lived, narrow-band bursts superposed (storm bursts, type 1 bursts). With equipment of high resolving power these bursts may be resolved into pips, each lasting for a fraction of a second only.
