Goal
Development of a 3D model for the structure of CMEs based on the analysis of multi-wavelength space- and ground-based observations. Tests of the model validity through STEREO, SOHO multipoint observations and visualisation of the model for scientific demonstration and public outreach purposes.
Successes
Until now, more than 80 CMEs have been identified in the STEREO COR A,B data at separation angles of the satellites of up to 90 degrees. They are stereoscopically analysed based on a ray-tracing code modelling the electron density distribution. The results yield the first ever obtained 3D view of CMEs.
Exceptional Discoveries
In December 2008, for the first time ever, a CME could be directly tracked continously from Sun to Earth using STEREO and ACE observations.
Progress so far
UNIGRAZ (Manuela Temmer)
A geometrical triangulation method for the determination of CME directivities was developed, which can be used for classical leading edge measurements combining observations from STEREO-A, STEREO-B, and LASCO. The method was applied to selected events.
UNIGOE (Volker Bothmer, Ansgar Reiners)
The electron density distribution of CMEs observed by STEREO, SOHO is modelled and compared with the magnetic field structure of the source regions. The results will provide the first 3D view of CMEs and unravel their evolution to Earth's orbit which will be crucal for reliable space weather models.
Problem areas
None.
Suggestions for spin-off, collaboration or improvement
Timeline for the delivery of the visualisation product needs to be extended to optimise the outcome.
