Magnetic energy acumulation in the coronal current sheetfor a solarflare NOAA 10930 0 6 .1 2 .2 0 0 6 GOES 1 2 J Время (часы) 17:39:30 Bn ri25o г 4.18 1022Mx г ' 2.241022Мх lA s s * Figure 4. Solar flares are not connected with the strong change o f magnetic disturbance in the active region Conclusion The current sheet is the only known object in space, which is able to accumulate magnetic energy and then to release it explosively. Current sheet in the geomagnetic tail is causing geomagnetic storms. The role of the current sheet in the Earth's magnetosphere became known only after the spacecraft measurements whose orbits have crossed the geomagnetic tail. To investigate such possibility in the solar flares is still lacking the measurements in the corona, and the only approach to the analysis of the magnetic field configuration in the flare process is the three-dimensional MHD numerical simulation of the field dynamics at the initial and boundary conditions taken from the measurements in the pre-flare behavior of AO.
