Magnetic clouds observed by STEREO

We present the results from an attempt to merge in-situ magnetic cloud reconstruction techniques with white light heliospheric imager 3-D reconstruction techniques. This has been accomplished to serve two purposes: 1) to identify which features of interplanetary coronal mass ejections (ICMEs) are most prominent in heliospheric imagers; 2) to set some standards from which scientific revelations about ICMEs may be achieved. We combine the magnetic cloud model of Romashets et al. (A&A, 2007) with the elliptical force-free solution (Vandas & Romashets, A&A, 2003) and the recently-developed Tappin-Howard (TH) model (Tappin & Howard, SSR, 2009) for heliospheric imager ICMEs. Along with an analysis of the kinematic evolution of the CME we compare the 3-D structures of each of the features in the heliospheric imagers with those of the magnetic cloud.
