The Solar Mass Ejection Imager (SMEI) was launched in January 2003 into Earth orbit. It observes sunlight that has Thomson-scattered from heliospheric structures of time-varying density. SMEI is designed to observe heliospheric structures such as coronal mass ejections (CMEs), corotating structures and shock waves to elongations greater than 90 degrees from the Sun. Such a near-Earth imager can provide up to three days warning of the arrival of a CME from the Sun. In combination with other imaging instruments in deep space, or alone by making some simple assumptions about the outward flow of the solar wind, SMEI can provide 3D reconstructions of the heliospheric structures that it observes. We show images of several CMEs observed with this instrument and low-resolution reconstruction analyses using the SMEI data for each event. The 3D reconstructions and heights for these events are compared with elongation-time plots of the same CMEs to estimate true speeds and line-of-sight locations for each CME.
