โœฆ Synopsis

One of the widely accepted models for solar radio pulsations invokes radial oscillations of a magnetic flux tube. Due to acoustic, radiative damping, this theory does not easily explain the long length of the pulse trains, the large modulation depths or the great stability of the pulse repetition rate often observed. Torsional waves efficiently modulate synchrotron emission, and since they do not undergo radiative damping, can produce stable pulse repetition rates and long pulse trains.

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
