The Sun Earth Connection Coronal and Heliospheric Investigation (SECCHI) is the remote sensing component of the STEREO mission to explore the source, initiation, and propagation through the heliosphere of Coronal Mass Ejections (CMEs). To achieve this goal, SECCHI must continuously observe CMEs from two different perspectives beginning with the pre-event coronal configuration and ending with the propagation of the event out of the inner heliosphere. Thus, each of the two STEREO observatories carries a suite of SECCHI telescopes with 5 different fields of view providing an uninterrupted view of coronal and Heliospheric phenomena from the solar chromosphere to 1 AU. This is the first panoramic view of the inner heliosphere dedicated to observing the spatial and temporal scales characteristic of CMEs at elongation angles from 0 to almost 90 degrees.
We present first results from the SECCHI imaging suite with emphasis on the unprecedented panoramic views of the heliosphere. We show direct observations of CMEs and the solar wind from initiation on the Sun throughout the inner heliosphere to 1 AU. The SECCHI suite performance exceeds that necessary to achieve the Level 1 STEREO science objectives. Thus, as the STEREO spacecraft separate to provide views from different directions we can anticipate breakthrough observations for issues currently unresolved by plane-of-sky projections through optically thin structures.
The most current information on SECCHI can be obtained from the STEREO mission website at http://stereo.gsfc.nasa.gov and the SECCHI website at http://secchi.nrl.navy.mil. The NRL participation in the STEREO mission is supported by NASA under S-13631-Y, and by the Office of Naval Research.
