  17. 26 April 2008 CME Summary: The SMEI 3-D analysis shows the density enhancement and measures the mass of the 26 April 2006 CME and shows its shape, 3-D extent and its interaction with the pre-existing co-rotating structure.

  23. Summary of the study of 4 shocks: The 3-D SMEI analyses now show the extent of density enhancements behind shocks in pretty-good agreement with in-situ spacecraft proton densities. The shock sheaths observed in the SMEI data are highly variable in latitudinal andlongitudinal extent. In SMEI, the shock density enhancements analyzed to date generally do not show a uniform shell-like extent. Attempts to compare the density enhancements behind shocks from brightness and in situ measurements show not only the agreement in the these two types of analyses, but also the differences in the different instruments that measure proton density in situ.

  28. 17 January 2010 CME Summary: The SMEI 3-D analysis shows a loop of material. Does this agree with the flux rope cylinder orientation and show the approximate orientation of the filament on the solar surface?

  29. Overall Summary: We have now devised a wealth of “tools” to understand and analyze the SMEI image data, to ascertain how well the SMEI 3-D reconstructions work, and to compare these with multi-spacecraft observations. Considerably higher-resolutions are available if we are able to use more of the SMEI data for the 3-D analyses. A new SMEI for precision photometry – a view of the whole sky in a more benign space environment than 840km polar orbit would be helpful.
