Radio Pulsations associated with the Solar flare of 1982 April 14

Abstract

We report here the H-alpha observations of a large and complicated flare of optical class 2B which occured on 1982 April 14. The flare showed significant activity for several minutes prior to its impulsive phas, as evidenced by the dynamic spectrum of the associated radio event taken simultaneously at Culgoora. The dynamic spectrograms showed strong chains of pulsating bursts superimposed upon the type IV continuum in close associated with intermittent type III burst stroms in metric and decametric bands. Traces of remote brightenings were also seen at a distance of ~ 10/sup5/ km from the main flare site in its declining phase.
