Multi-spacecraft observation

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.

The shock expansion accounts for the times of SEP injections and the injection delay between the field lines leading to L1 and STEREO A.
