Scientific paper

The Solar Mass Ejection Imager (SMEI) has been operating since February 2003. At the University of California, San Diego (UCSD), a series of editing steps and a tomography program removes zodiacal light, high-energy-particle hits, and aurorae the SMEI data; and generates reconstructed sky-map images and three-dimensional (3-D) volumetric densities shortly after the SMEI CCD images become available. The removal of a long-term base allows us to map the 3-D density extents of coronal mass ejections (CMEs) and co-rotating structures, and measure the density variations of these structures including estimates of their continuity and the extent of density enhancements behind interplanetary shocks. We match our analysis with the in-situ density columns that pass the spacecraft near Earth as well as near the twin Solar TErrestrial RElations Observatory (STEREO) spacecraft. Here we concentrate on Thomson-scattered white-light SMEI observations of the 3 April 2010 halo CME, contrasting it to the studies of previous CME events that provide similar Sun-to-Earth analyses.
