The Solar Mass Ejection Imager (SMEI) has been operating nearly continuously since “first
light” on the Coriolis spacecraft in early February, 2003. We present the current state of the
SMEI database maintained and stored on UCSD/CASS Web servers. The up-to-date UCSD
database includes individual SMEI CCD data frames from each of the three SMEI cameras
since launch as well as single-orbit full-sky maps in a sidereal reference frame that preserve
the original resolution and photometric precision. Further processing of the SMEI data for the
whole data set has allowed the removal of zodiacal cloud brightness, auroral signals, bright
stars, and the sidereal background. A Web interface to this latter data set describes the
database and allows display of these maps in sun-centered ecliptic coordinates, either directly
or as running differences. “Quick-look” skymaps are now displayed as real-time difference
images on the UCSD website within a few hours of their arrival from the instrument. Further
processing provides these data free from planetary-, moon-, and auroral-light contamination
so that they can be used in tomographic 3-D analyses. These 3-D analyses are presented on
the Web as up to date as possible (usually within a month of their being available). Current
plans are to provide these higher-level products additionally in “forecast” mode, allowing
real-time updates of in-situ density measurement forecasts at Earth up to a few days ahead of
the present.
