Three-Dimensional Polarimetric Imaging of Coronal Mass Ejections
Thomas G. Moran1,2* and
Joseph M. Davila1
We present three-dimensional reconstructions of coronal mass
ejections (CMEs), which were obtained through polarization analysis
of single-view images recorded with the use of the Large Angle
and Spectrometric Coronagraph (LASCO) C2 coronagraph on board
the Solar and Heliospheric Observatory (SOHO) spacecraft. Analysis
of a loop-like CME shows a complex three-dimensional structure
centered at 40° from the plane of the sky, moving radially
at 250 kilometers/second. Reconstruction of two halo CMEs suggests
that these events are expanding loop arcades.
