Abstract
The Solar Mass Ejection Imager (SMEI) observes the increased brightness from the density enhancements behind interplanetary shocks that are observed in situ near the Earth. We use the University of California, San Diego time-dependent three-dimensional-reconstruction technique to map the extents of these density enhancements. As examples, we examine the shock density enhancements associated with several well-known coronal mass ejections including the 28 October 2003 (Halloween storm) event. We compare these density enhancements with reconstructed velocity observations from Solar-Terrestrial Environment Laboratory interplanetary scintillation (IPS) observations when these are available. Volumetric-differencing techniques available from the SMEI analyses show that the outer portion of a larger increase in heliospheric density is often what is observed in short-time image brightness subtractions from these data.
