Plots are in GSE (geocentric solar ecliptic) coordinates, so Earth is at [0,0], the Sun is at [1,0]. The plot is the projection of the orbit on the ecliptic plane.
3th and 4th orbit in EMP: 6 RS windows, in the first orbit S and N windows reach max latitude 28º, in the 2nd orbit they reach 31º already; perihelia at 0.33AU and 0.3AU.

Proposal
MTP15 - 1st South:
MTP15 - 1st Perihelion:
- L_FULL_MRES_MCAD_Flare_SEPs requires perihelion and medium TM . Close to solar max so higher chance for flares.
MTP15 - 1st North: also suitable for L_SMALL_HRES_HCAD_Fast-Wind (high latitude and close in)
MTP15 - 2nd orbit:
- Use the last orbit (3 windows) for L_BOTH_LRES_MCAD_Pole-to-Pole SOOP.
- Alternatively or in combination, use those for L_SMALL_HRES_HCAD_Fast-Wind! This MTP has good TM to support it, it falls during declining phase with higher chance on extended CHs. Also best quadrant for context from Earth.
- Alternatively or in combination, these 3 RSWs can also be favourable to run R_FULL_HRES_HCAD_Density-Fluctuations with Metis leading (thus disk centre pointing!)
- Perihelion+North is also suitable for L_FULL_MRES_MCAD_Flare_SEPs: benefits of close distance + radial alignment with Earth. SPP would be big asset as well.
MTP15 - 2nd perihelion & 2nd North:
- close to the Sun at Earth side, so suitable for R_SMALL_HRES_HCAD_AR-Dynamics
MTP15 - 2nd North: also suitable for L_SMALL_HRES_HCAD_Fast-Wind (high latitude and close in)
