Fine structure of the S-component spectrum of the solar radio emission in the frequency range 5.0?7.0 GHz

Abstract

Fine structure observations of the frequency spectrum of the S-component in the solar radio emission are described. Measurements were carried out in August 1976 and August 1977 using a 22 m parabolic antenna and a radiospectrograph operating over the frequency range 5.0 to 7.0 GHz, with the resolution 60 MHz. Measurement techniques are described. Fine structures (150-800 MHz) as great as 20% of the local source radiation level were observed in radio emission spectra of a number of these sources. The spectrum structures observed were changed in the process of active region development.

Spectral Polarimetric Observations of the Sun by the VIRAC RT-32 Radio Telescope: First Results

“…Spectral polarimetric observations of active regions of this kind could now be performed. A set of closely adjacent frequencies of the spectral polarimeter is an evident advantage for the observations of the fine spectral structures for revealing and analyzing of some possible current sheets of solar active regions (Kaverin et al 1980) Routine spectral polarimetric observations by means of VIRAC radio telescope RT-32 will give us more valuable information about the microwave emission of the Sun.…”

A frequency-agile interferometer for solar microwave spectroscopy

“…High spectral resolution measurements have been reported by Soviet workers using the RATAN-600 telescope between 5 and 7 GHz (Kaverin et al, 1979). At lower frequencies the dynamic spectra of metric and decimetric bursts have been observed with high spectral and time resolution by many instruments (Kr~iger, 1979).…”
