We are designing a Solar Mass Ejection Imager (SMEI) capable of observing Thomson-scattered signals from heliospheric density features from a spacecraft situated near 1 AU. The imager is designed to trace these features, which include coronal mass ej

Interplanetary scintillation (IPS) measurements of the ‘disturbance factor’ g, obtained with the Cambridge (UK) array can be used to explore the heliospheric density structure. We have used these data to construct synoptic (Carrington) maps, repr
