STEREO: Difference between revisions

* '''Sun Earth Connection Coronal and Heliospheric Investigation (SECCHI)''' has five cameras: an extreme ultraviolet imager (EUVI) and two white-light [[coronagraph]]s (COR1 and COR2). These three telescopes are collectively known as the Sun Centered Instrument Package or SCIP. They image the solar disk and the inner and outer [[solar corona|corona]]. Two additional telescopes, [[heliospheric imager]]s (called the HI1 and HI2), image the space between Sun and Earth. The purpose of SECCHI is to study the 3-D evolution of [[coronal mass ejection]]s through their full journey from the Sun's surface through the corona and interplanetary medium to their impact at Earth.<ref name=inst>{{cite web |url=http://www.nasa.gov/mission_pages/stereo/spacecraft/index.html |title=STEREO Spacecraft & Instruments |publisher=NASA |date=March 8, 2006 |access-date=May 30, 2006}}</ref><ref>{{cite journal |title=Sun Earth Connection Coronal and Heliospheric Investigation (SECCHI) |journal=Advances in Space Research |first1=R.
