Investigating a Complex X-class Solar Flare Using Magnetic Field Modeling
Abstract
We will present the investigation of a complex X-class flare occurred in NOAA Active Region 11283 on 2011 September 6. This flare is associated with two filament eruptions and a coronal mass ejection (CME) with speed of 575 km/s. AR11283 contains mainly two bipoles, a large decaying bipole and a small “L” shape emerging bipole with sunspots. The main eruption initiated and occurred in the small bipolar region. Multiple flare ribbons are observed during the eruption. We studied the structure and dynamics of the erupting filaments and flare ribbons observed by SDO/AIA and Hinode/XRT as well as the dynamics of the photospheric magnetic fields observed by SDO/HMI. We also constructed magnetic field models using the flux rope insertion method, in order to understand how the eruption is triggered and how the flare ribbons are formed during the eruption.
