| Abstract: | Solar flare films obtained on the TRACE spacecraft with a resolution of 1″ in the 160-nm (CIV) band with a frame separation of 2 s are examined. It has been indicated that the flare scenario is determined by the dynamics of numerous structures of about 1000 km in diameter. The fractal nature of the flare is confirmed. A self-organized criticality (SOC) mechanism is proposed to explain the flare formation and development. The most probable source of the flare energy is considered to be the chain of three-dimensional solitons. |
