Longitudinal factor in the spatial distribution of energetic solar flares

Discrete location of large flares near zero Carrington longitude results in artificial breaks within physically related flare clusters. This effect is eliminated by using the data presentation algorithm, which results in the conclusion that drifting zones of intensified sunspot formation (concentrated cores of activity complexes) and energetic flare generation exist in either hemisphere. The indicated L zone is hypothetically related to a non-asymmetric relic solar magnetic field or to the regions where large-scale convective cells, extending to the convective zone bottom, originate.
