Abstract:
We report here the H-alpha observation of a large and complicated flare of optical class 2B Which occurred on 1982 April 14. The flare showed significant activity for several minutes prior to its impulsive phase, 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 association with intermittent type III burst storms in metric and decametric bands. Traces of remote brightenings were also seen at a distance of ~ 10⁵Km from the main flare site in its declining phase.
