Abstract

IN the radio-frequency spectrum, solar radio bursts have been classified according to their dynamic structure. Information on the velocity of shock waves or the solar corpuscular stream as well as on the physical mechanism of the radiation has been obtained by this recording method. Another technique for studying the mechanism of solar radio radiation is to observe the modulation structure of bursts and the quiet Sun at discrete frequencies. Jager and Veer1 studied solar radio transients by recording 200 Mc./s. radio noise on fast paper tape. Their observations were concerned with the time duration and distribution of radio-pips, their bandwidth and the presence of the echo phenomena.
