New aspects of the April 27, 1981 flare
Abstract
Very interesting radio bursts, observed during the well-known solar flare of April 27, 1981 are presented. While the sequence of reverse drift bursts, U-bursts and radio flux depression on 9.375 GHz can be explained within the beam bombardment and evaporation model, the narrowband dm-spikes uniquely organized in "necklace" structures seem to indicate the interaction of flare loops. Arguments in favour of the plasma emission model of narrowband dm-spikes were found.
