Abstract:

Pulsations with large amplitude and duration have been observed during the hard X-ray and microwave radio bursts associated with the 7 June 1980 approx. 0312 UT solar flare. The high time resolution measurements of 20-800 keV X-rays were made with the X-ray spectrometers aboard the ISEE-3 and P78-1 spacecraft. The radio measurements, covering metric to microwave wavelengths, were made at the Nobeyama and Toyokawa observatories in Japan. The temporal evolution of the X-ray and radio spectra and the polarization and spatial structure of the microwave source have been examined. The following interpretation is found to be consistent with the observations 1 the variations in the electron accelerationinjection spectrum are responsible for the observed variations in the hard X-ray and microwave emissions 2 the locations of the hard X-ray and microwave sources are probably different, the X-ray source being located at a lower altitude.
