Modeling And Measuring The Flux Reconnected By The Two-ribbon Flare On 2004-11-07
Abstract
Observations of the large two-ribbon flare on 2004-Nov-7 made using SOHO and TRACE data are interpreted in terms of a three-dimensional magnetic field model. This model predicts the amount of flux reconnected during the flare and the energy it would release. These values are compared to the flux swept up by the flare ribbons observed by TRACE in 1600 A and the energy release inferred by the GOES light curves. The helicity of the model field may be independently compared to the helicty injected by photospheric motions during the buildup to the flare. The model also predicts the sequence in which the reconnections should occur. This in turn provide insight into the conversion of mutual helicity into self-helicity during the production of a twisted flux rope.This work is supported by NASA Grant NAG5-10489 and DoD MURI grant.
