Scientific paper

With STEREO spacecraft separation now at greater than 40 degrees, we can examine 3D reconstructions using white light coronagraph data to constrain the observed CME underlying morphology and kinematics. We reconstruct the electron densities for the December 31, 2007 CME and associated streamer using individual pairs of STEREO observations from the COR 2 coronagraph, and then add a third viewpoint with LASCO coronagraph observations from SOHO. We also examine kinematics for the December 31 CME from successive reconstructions of the event during its development. Our tomographic technique uses the PIXON algorithm for our reconstructions. We overlay these results with forward reconstruction of a model flux rope and with geometric line-of-sight mass integrations. We also compare these results with other 2008 CMEs, and finally, illustrate how the community can use our publicly available reconstruction toolkit.
