Space observations of solar radio bursts have provided the following information:– From a single spacecraft:Measurements within the burst source or close to it: fundamental and harmonic type III radio emission, the corresponding plasma waves and spectra of the exciting electrons.– From a spacecraft and the earth or from two spacecrafts:A better evaluation of the influence of the ionosphere on some ground-based observations.Measurements of the beaming of the emission which yield constraints on the radiation mechanism and/or the role of coronal propagation in determining the source size and directivity (type I and III's).Measurements of the differential time delay which yield for type III:At short (m- and dam-) wavelengths, some evidence of group delays,At long (hm- and km-) wavelengths one coordinate of the source.Complete (3-dimensional) localization of the source at long wavelengths and therefore maps of the heliosphere magnetic field and electron density as well as the source size and, in the future, its polarization.The results of these observations and their interpretation are reviewed and discussed.

Fast Drift

Observations are described of solar radio burst spectra in the frequency range 25-100 MHz with a time resolution of 0�02 sec. The types of bursts that were observed included (1) fast drift storm bursts with a mean frequency-time slope of 1�9 MHzsec-1, a mean bandwidth !!.f'"-' 0�03 MHz, and a mean duration !!.T of 0�6sec; (2) drift pair bursts with dffdt = 1�2MHzsec-1 and !!.f= 0�45 MHz; and (3) split pair bursts with dffdt = 0�08 MHzsec-1, !!.f = 0�05 MHz, and !!.T = 1�4 sec. In addition, chains of split pa.ir bursts were frequently observed, the chain resembling a type I burst with fine structure.

Radio Event

The type II solar radio bursts produced by a shock wave passing through the solar corona are one of the most frequently studied solar activity phenomena. The scientific interest in this type of phenomenon is due to the fact that the presence of this radio event in a solar flare is an almost certain indicator of a future geophysical effect. The origin of the shock waves which produce these bursts is not at all simple; besides the shocks which are generated as a result of a strong energy release during the impulsive phase of a flare, there are also the shocks generated by a coronal mass ejection or the shocks which appear in the interplanetary space due to the supplementary acceleration of the solar particles.
