  1. 3D Morphology of CME-driven Shocks(work in progress) V. Ontiveros, A. Vourlidas, A. Thernisien

  2. Geometric shock model Modeling LASCO Shocks Ontiveros & Vourlidas 2009

  3. Modeling LASCO Shocks Ontiveros & Vourlidas 2009 Positional Information of CME Shock

  4. SECCHI Forward Modeling (CME + Shock) COR2-A COR2-B CME at W109 Shock at W109

  5. December 31, 2007 CME – Direction

  6. SECCHI Shock Modeling: 12/31/2007 Event

  7. SECCHI Forward Modeling (CME + Shock) COR2-A COR2-B

  8. SECCHI Forward Modeling (CME + Shock) COR2-A COR2-B CME at E93S15 h = 7.9 Rs Shock at E93S06 h = 8.5 Rs

  9. SECCHI Forward Modeling (CME + Shock) COR2-A COR2-B CME at E93S16 h = 10.6 Rs Shock at E93S01 h = 11.3 Rs

  10. SECCHI Forward Modeling (CME + Shock) COR2-A COR2-B CME at E93S18 h = 12.8 Rs Shock at E93S00 h = 13.1 Rs

  11. Asymmetric shock expansion? The large-scale Coronal Magnetic Field affects the shape/propagation of the white light shock. GONG / Synoptic Maps

  12. Conclusions • We can estimate the 3D morphology of the shock using forward modeling • We can derive direction, speed, size of the shock • Some events show deviations from a symmetric shock shape. This points to influence of large scale magnetic field on the shock properties.

  13. CME-driven shock front compressed material LASCO: 1013 km/s COR2: 735 km/s streamer deflected SECCHI/COR2A
