AB: The Solar Mass Ejection Imager (SMEI) experiment on the Coriolis spacecraft has been obtaining all-sky, white light images on each 101-minute orbit for over 1.5 years. SMEI is fixed to the spacecraft and views the sky above Earth using sunlight-rejecting baffles and CCD camera technology. When fully calibrated, sky maps of structures having enhanced electron density in the inner heliosphere can be produced. We present some preliminary results of analysis of SMEI observations of coronal mass ejections (CMEs) traveling through the heliosphere. These include observations of about 100 CMEs during the first full year of observations. At least 3 of these, observed as frontside halo events by LASCO, were observed by SMEI propagating to and beyond 1 AU, and were associated with major geomagnetic storms at Earth. We will show examples of the CMEs and present a summary of their characteristics. We will also show some 3D reconstructions using both interplanetary scintillation (IPS) and SMEI data using techniques being developed to analyze the evolution of heliospheric plasma, including transient CMEs and corotating dense regions.
