- Determine the velocity, acceleration profile and the mass of the transient slow wind flows.
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.
(To be moved to an overarching section (to be created) of characterisation of the solar wind together with other general in situ objectives).
