There have been 6 SECCHI consortium meetings, most with topics pertinent to space weather or with separate space weather sessions.
1st SECCHI consortium meeting at Easton, MD, November 2000
2nd SECCHI consortium meeting at Abingdon, UK, July 2001
For decades, the search for answers to these fundamental questions has preoccupied solar and space physicists and has driven the plans for all Sun Earth Connections (SEC) missions.
The importance of coordinating the observations, as well as their analyses, can hardly be overemphasized. We have never before had an opportunity to observe from two well-separated viewing points. The stereoscopic techniques and their results will be entirely new; we can expect to be learning while observing. Furthermore, the opportunity will not be a static one, as the viewing characteristics will change continuously with the growing separation angle between the two spacecraft.
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.
