Stereoscopic Results from NASA's STEREO Mission

Coronal mass ejections (CMEs) play a major role in the dynamics of Earth's geospace. However, the origin, magnetic configuration, and evolution of these solar manifestations are not well understood. The current twin- spacecraft mission, Solar Terrestrial Relations Observatory (STEREO), has provided images for stereoscopic analysis of coronal features. A catalog of CME events and associated low coronal (EUVI) activity that occurred in May 2007 was created to help understand the origin of CMEs. Three CME events, May 15th, 20th, 22nd, were selected for further investigation using the Sunloop software tool. This tool uses a "tiepointing" method and triangulation to do 3D reconstruction of coronal loops and prominences from simultaneous stereoscopic images from the SECCHI image suite on STEREO. The catalog and the results of the software tool analysis on the three events will be presented. Qualitative analysis of SECCHI/EUVI data using anaglyphs will also be presented.
