Studies on Halpha and SXR flares in relation to Type III metric bursts

Abstract

A study was made on Halpha and SXR flares in relation to Type III metric bursts. The interrelationship between Halpha and SXR flares was examined by grouping the events into two categories, (i) the events associated with Type III metric bursts, and (ii) those not associated with Type III metric bursts. Important results obtained are: (a) the drift rate of Type III bursts increases with the increase of integrated intensity of Halpha-flares, (b) the intensity of SXR flares increases with the increase of intensity of Halpha flares, this increase becomes steeper in the presence of Type III bursts, (c) the SXR flare intensity decreases with the increase of asymmetry in duration of Halpha flares, this sort of decrease is also steeper in the presence of Type III bursts.
