| Abstract: |
The evolution and properties of the GOES C7.2 class solar flare observed in the NOAA 8088 active region on 25 September 1997 were studied. The observed properties of the flare are consistent with a model, in which the releases of the energy were caused by two successive X-type interactions of an expanding loop with two higher located loops. Before the second interaction the lower loop was pushed from below by the eruption of the magnetic field manifested by eruption of a system of Hα threads. The total energy stored in the magnetic fields of three interacting loops was almost one order greater than the whole thermal energy contained in the loops. While the flare occurred in a stable system of magnetic loops, which apparently survived the flare, we find that only a small fraction of the energy of the magnetic fields was converted into the thermal energy. |
