[2.04] Nonlinear Force Free Field Models of AR 0486

J.M. McTiernan, H.S. Hudson (Space Sciences Lab, UC Berkeley), T.R. Metcalf (Lockheed-Martin Solar and Astrophysics Lab)

In this work we present nonlinear force free field (NLFFF) extrapolations from vector magnetograms of AR0486 taken before, during and after the X11 flare of 29 October 2003. The extrapolations will be used to interpret the different source patterns and motions seen in RHESSI and TRACE images of the flare. In particular we will examine the footpoint motions observed in the flare by RHESSI, and also the expansion and other changes in the high temperature thermal sources visible in low energy (less than 20 keV) RHESSI images and TRACE 195 A images.

This work is funded by NASA contract NAS 5-98033.
