1. Coronal waves: hot structure and footprint of CME

3. 10 10 K >Temperature > 10 4 K, SXI filter ratio gives 3-6 10 6 K Be Thick Thin

4. Last brightening is footprint of CME leg

5. Model:expanding flux rope Delannée et al. (in press) projection view top view weaker & stronger J sheets Electric current shell formed in the dynamic phase when u z < c A

6. Model: in multipolar magnetic field

7. Conclusions Coronal waves are hot structures. They stop at coronal hole, where the CME leg footprint is. They are possibly signature of opening of magnetic field lines near the solar surface.
