1.2.2 What mechanisms heat and accelerate the solar wind?

East or West limb, possibly close magnetic loops, helmet streamers

 6 hours

Earth in quadrature with Solar Orbiter.

Different phases of solar cycle.

3.2.0 What controls the escape of the particles to the heliosphere?

East or West limb, possibly erupting AR close to the limb

6 hours

Earth in quadrature with Solar Orbiter.

WOLs and PASS.

Modelling to find best candidate source regions. 

Mosaic to map larger region for maximise the linkage with the source on the Sun.

Radial or quadrature alignment with SPP is a plus.

3.2.1 How do energetic particles scatter and move along the interplanetary magnetic field?

East or West limb, possibly erupting AR close to the limb

6 hours

Earth in quadrature with Solar Orbiter.
