1 Reames, Ng, Tylka 2012 Sol Phys Multi-spacecraft observation

2 Reames, Ng, Tylka 2012 Sol Phys Multi-spacecraft observation

3 CME/SEP Connection Plasma flow in a CME controls where and when the field lines connect to the shock and hence the observed SEP intensity variation. Such multi-spacecraft observation will be made by Solar Probe Plus and Solar Orbiter near the Sun with far greater precision and with concurrent CME observation.

4 2011 Mar 21 Intensity time profiles at STEREO A Ng et al In prep.Rouillard et al May, ApJ

5 CME Observation Rouillard et al May, ApJ

6 The shock expansion accounts for the times of SEP injections and the injection delay between the field lines leading to L1 and STEREO A. Rouillard et al May, ApJ

7 L1 and STEREO A pre-shock proton energy spectrum Ng et al In prep.Rouillard et al May, ApJ

8 Model SEP release time profiles at shock
