- Disentangle the spatial and temporal variability of the slow wind: comparison of the variability of the slow wind on a number of orbits, with varying relative spacecraft-Sun longitudinal speeds at the same distance. [multiple orbits, radial dependence] [Compare to other spacecraft – radial alignments.]
This objective is part of the general characterisation of the solar wind and can be addressed by the in situ instruments (with the SOOP I_DEFAULT). No specific operational planning is needed. However, it will benefit from joint observations with PSP and L1, especially during radial alignments.
