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.
2nd orbit in EMP: 3 RS windows, S and N windows reach max latitude 28º, farther perihelia: at 0.33AU.

Proposal
MTP14 - perihelion: another good opportunity to schedule 20-30mins of R_SMALL_HRES_HCAD_RS-burst at perihelion day, at least if you can hold onto the data until the big underrun. Together with the North window this is a time with very high TM downlink, and could be suitable to schedule a few instances of R_SMALL_HRES_HCAD_RSburst to enhance chances of catching energetic particle events (see 3.2.6 Effects of energetic particles propagating downward in the chromosphere).
- MTP14 - NorthB also suitable for L_SMALL_HRES_HCAD_Fast-Wind (high latitude and close in)
