Effect of Different Factors on the Solar Flare Energy

The factors affecting the energy of the solar flare are being studied. The model of particle acceleration in the magnetic X-singularity has been studied. It has been found that the flare energy depends mainly on the flow of electrons into the acceleration zone. The change in such a flow is determined by the size of the acceleration zone. It has been calculated that for a chromospheric flare source, the vertical length of the acceleration zone has varied from ∼100 to ≈2 × 103 km and its diameter varies from ∼1 to ≈100 km.
