Drifting spikes—a new species of solar radio bursts

Abstract

OBSERVATIONS of solar radio bursts of spectral type IV have revealed the presence of a complicated fine structure in the emission at metric wavelengths1–4. It would be interesting to extend high resolution spectral observations to decimetric wavelengths to explore the structure of radiation which is generated at lower heights in the solar atmosphere, and is, therefore, closer to the site of the associated optical flare. We report here a new species of fine structure bursts, drifting spikes, which have been observed in the 500 MHz frequency region.
