Method of CME detection
|
Use of the Synoptic Maps as a new support :
- Global vision in time.
- Specific characterization of CMEs is possible.
- Interaction of CMEs with streamers.
An automatic method :
- Detection based on objective criteria.
- Fast detection process.
|
 |
- Signatures of CMEs are very often superimposed on the streamer belt and sometimes create discontinuities in it.
- Most of CMEs present characteristic signatures : conspicuous vertical, narrow streaks.
|
|
- Our Automatic Detection Method consists in extracting the signal of CMEs from the synoptic maps and involves four steps.
- Detection is computed on synoptic maps built from 3 up to 5.5 solar radii per step of 0.5 solar radius.
