โœฆ Synopsis

The effects of scattering and refraction on radio waves in the solar corona are considered for several different coronal models. By considering a source near the plasma level in a spherically symmetric corona and in a streamer enhancement superimposed on a spherically symmetric corona we obtain results relating to bursts of types I, 1I and III.

From the results of these calculations it is suggested that estimates of coronal density derived from observations of type II and type III bursts are too high by a factor of 1.5 to 2; that there is considerabe doubt about the accuracy of coronal temperatures estimated from rate of decay of type III bursts; and that the duration of, and velocity dispersion in, the exciters of tyl~e III bursts have probably been over-estimated. The effects of scattering and refraction are also considered as they relate to observations and interpretations of harmonic source radiation patterns, drift pair bursts and spike bursts.

Three solar outbursts which show pulsating radio emissions at metric waves (239 MHz) are examined. The behaviour of the single frequency, high-time resolution records and the spectral diagrams seem to indicate that such phenomena are peculiar phases of type IV radiation, perhaps connected with absor

The scattering of radiowaves in the outer solar corona is discussed. Results are given of the decametric wave observations. In the theoretical analysis both regular refraction and the gradients in the electron density fluctuations are considered. The theory is in satisfactory agreement with the expe

Some properties of solar radio bursts observed at the Earth are mainly due to propagation effects in the corona, A radio echo of short-time narrow-band bursts is observed by a decameter radioheliograph on the basis of UTR-2 antenna. Propagation effects are manifested in the marked regular change of

Cyclotron radiation (its frequency spectrum and polarization) of thermal electrons in a neutral current sheet is considered. It is shown that cyclotron radiation is able to escape only from a thin edge of the sheet where the magnetic field is practically homogeneous. Due to this, the frequency spect
