摘要: Field variations in the region of eruptive event June 7, 2011, associated with filament eruption (FE), flare, and coronal mass ejection are studied based on vector measurements photospheric magnetic field SDO/HMI instrument. Variations module (B), radial (Br) transverse (Bt) components induction, inclination angle (α) lines to direction from center Sun analyzed. It is shown that strongest changes before were located near base southeastern leg filament; after beginning event, they CME flare region. suggested FE two episodes strong rapid variations: slow rise its sudden acceleration. For first time, angles over time different parts detail. was found decrease vicinity channel during filament, increase sharply neutral line.
