Energetic flare zones on the Sun

Abstract

In this investigation, we have studied the latitudinal, longitudinal (northern and southern hemispheric) distributions based on 1737 major flared observed during solar cycles 19 and 20 (see subsequent paragraphs) and have arrived at some interesting results which go to show that as far major flares are concerned latitudewise 11-20° belts, and longitudewise 5-8 places are most prolific in producing major flared in each hemisphere. During the above cycles at least 5 flares zones are present in each hemisphere. In fact these zones seem to produce more that 50% of the total number of energetic flares investigated by us and occupy only <4% area of the Sun
