Quasi-periodic solar emission has been observed with a radio spectrograph operating at 18-28 MHz during weak decametric continuum on August 22, 1972. The continuum activity was observed simultaneously on fixed frequency receivers at 18 MHz and at 26 MHz. The pulsations showed a mean period of 4 s an

โฆ Synopsis
Observations are reported of radio-pulsations at din-wavelengths. The pulsations are quasiperiodic with a period of 0.5 s, they have a bandwidth > 300 MHz and show up to a 50 ~ enhancement of the underlying type IV continuum.

It is well known that the oscillating MHD waves drive periodic variations in the magnetic field. But how the MHD waves can be triggered in the flaring loops is not yet well known. It seems to us that this problem should be connected with the physical processes occurring in the flare loop during a so
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.
