A strong numerical modeling effort is as much an integral component of SECCHI as any one instrument. Given the complex spatial and temporal structure of the Sun and heliosphere, we must use modeling to extract from the data an accurate three-dimensional picture of the corona, Coronal Mass Ejections (CMEs), and the heliosphere.

Following table contains yearly and monthly breakdown of SECCHI images by APID. Each hyperlink reports number of actual images sent down via SSR1, SSR2, and SWx per detector for both spacecrafts. Since these statistics are generated using current data in SECCHI MySQL database tables, all images are available for query and download.
The telemetry statistics plots are generated using the science raw telemetry image volumes. These plots are percentages of EUVI, COR1, COR2, HI1, and HI2 telemetry bytes for all downlinked (SSR1, SW, RT) data as a percentage of total telemetery bytes on a monthly basis. SECCHI-A and SECCHI-B TM statistics are displayed side-by-side.
Science Operations Manual (DW) - This manual covers the flight software image scheduling and image processing, the planning tool interface, and other information useful for planning observations.

Welcome to the home page of the SECCHI 3D Reconstruction and Visualization Team. To organize the work of the scientific software preparations for launch of SECCHI on STEREO, scientific teams were formed from the SECCHI investigators. The other two science teams are the Space Weather and the MHD Modeling teams.
SECCHI is a suite of 5 scientific telescopes that will observe the solar corona and inner heliosphere from the surface of the Sun to the orbit of Earth. These unique observations will be made in stereo for NASA's Solar Terrestial Relations Observatory STEREO. The suite has three main parts.

In May 2024, Earth experienced some of the most intense geomagnetic storms seen in recent years. Solar eruptions that led to these storms were imaged by the SECCHI HI-2 camera on NASA STEREO-A. This image sequence shows the large CME front passing over Earth (far left, not to scale) along with concurrent Kp observations, which shows the Earth's geomagnetic response to the event.
Observations from the SECCHI HI-2 camera on May 12, 2024 (top), along with the concurrent "kp" geomagnetic activity index (lower). The location of Earth is as indicated on the left of the animation. [Credits: NASA/NRL/STEREO]
