About STEREO
The goal of the STEREO mission is in particular to enhance our understanding about the creation of solar eruptions and coronal mass ejections, to study the propagation of mass ejecta through the solar corona into interplanetary space and to investigate the associated acceleration of energetic particles.
Since the two STEREO space craft were launched in October 2006, we have for the first time the capability to observe processes on the solar surface and in the corona from two entirely different view directions, thereby enabling the reconstruction of the associated three-dimensional plasma distribution. In recent years, major topics in the MPS groups SoCo3D (Solar Corona in 3D) and CSI (Coronal Spectroscopy and Imaging) were
- EUV loops in active regions and how they compare to coronal magnetic field models
- Polar pumes and their distribution in coronal holes
- Distribution of magnetic flux and helicity across different active regions
- 3D shape of mass ejecta and their propagation and expansion in the Sun’s vicinity
- The invesigation of energetic particle fluxes in corotating interaction regions in the heliosphere inside 1 AU
