The Balance of the Current Filament in the Two Solar Active Regions

The variation and the vertical motion of the filament current in the two solar active regions McMath 10662 and McMath 10607 have been studied by using the equation of forec-balance in the vertical direction under the Kuperu-Raadu Model. The relation between the filament and the flare has been probed as well. The obtained results show that: (1)the prominence model with mirror current is fitted in description of eruption of a prominence; (2)the length of the filament probably has less relation to the height of the flare eruption, however it is possibly related to the energy restores in the filament.
