A. I. Podgomy and I. M. Podgomy ©■POINT MaxJ1 Fig. 3 a - Magnetic field configuration in the plane which contains the point Max j i with coordinates (0.46, 0.04, 0.445. and which is situated perpendicular to magnetic field vector B=(0.179, 0.04, 0.445). b - Magnetic field configuration in the plane which contains the point Max j 2 with coordinates (0.445, 0.105, 0.42) and which is situated perpendicular to magnetic field vector B=(-0.0086, 0.0264, 0.0819). с - Magnetic field configuration in the plane jc=0.445 which contains the point Maxj2. Conclusion The analysis of current sheets appearance in the magnetic field obtained by MHD simulations in the corona above the active region showed that the most likely the flare occurred May 27, 2003 at 02:53 in the active region NOAA 10365 is produced by the current sheet with center in Max ji (Fig. 1). Now, however, we can not exclude the appearance of this flare or another flare of this series, which is weaker, due to a current sheet in the vicinity of one of the points in the group that is located at an altitude of 30,000 - 40,000 km (Fig. 1). For a more precise answer to the question about the position of the flare May 27, 2003 at 02:53 it is required a similar graphical analysis of the results of the MHD simulations carried out in real time.
