โœฆ Synopsis


It is suggested that large scale oscillations of the Sun give rise to the periodic fluctuations observed in the quiet Sun at radio wavelengths. These fluctuations would be most readily observed from regions where there is a large gradient of electron temperature with electron density, and are thus more readily observed at cm wavelengths than at millimetre wavelengths.

The three-element interferometer of the National Radio Astronomy Observatory was used to observe the Sun at 3.7 and 11.1 cm wavelengths during the period June 5-9, 1973. The baselines of the interferometer were 900, 1800 and 2700 meters, with maximum angular resolution of 3" at 3.7 and 9" at 11.1 cm

On June 9, 1973, a flare associated burst was observed with the NRAO 3-element interferometer at 3.7 and 11.1 cm wavelength. The burst was of 'gradual rise and fall' type. Comparing the fringe amplitudes at 3.7 cm to the visibility computed for model flare regions we found that the precursor data ar

The solar burst of 13 July, 1986 at 2I cm wavelength was recorded with a time constant of 8 ms. In the course of the burst lasting for about 40 min there appeared distinct stages of the burst's evolution. They consisted of the pattern of energy release in flares which was proposed by Sturrock et al.

The results are given of observation of solar radio emission of the S-component at 8.15 ram-2 and 2.25 ram-2 made with the 22 m radio telescope of the Crimean Astrophysical Observatory. Solar radio images are obtained at both wavelengths. The data are presented of radio emission intensity and bright
