EFFECT OF CURRENTS IN SOLAR ACTIVE REGIONS

On the basis of several important observational facts which relate clo sely to the currents in AR5395, it is considered that the direct key f actor causing flare eruption is the enhancement of currents in the act ive region. In light of this idea, the energy storing process of flare phenomena is analysed and the motion equation as well as the energy e quation is established. According to the observational data of AR5395, the theoretical computation and discussion are performed on the possi bility of the occurrence of flares caused by current enhancement in th e active region. By and large, the results coincide with the observati onal results.
