- How shocks can accelerate electrons to relativistic energies (never observed for shocks near 1 AU)? Is a more energetic seed population necessary?
- SWA, SWA Normal Mode, several hours, perihelion, other instruments: RPW, MAG, EPD.
- MAG, MAG Normal Mode
- EPD: All sensors: spectra, composition, fluxes, directional information, together with IS instruments. Solar source identification by RS instruments (full disk imaging). Also coordinated multi-s/c SEP observation campaigns with SPP & other missions.
- METIS: (TO BE REVIEWED, not in line with RS full disk imaging requirement from EPD input. If finally approved, then to be possibly copied in all sections 3.1.4.*): Measurement of coronal outflow velocity and density in corona to identify the shock front. Measurement of shock passage timing relative to the flare occurrence.
- CME velocity maps
- CME density maps
