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.

7th orbit & most of 8th orbit in NMP: 5 RS windows, S and N windows reach max latitude 21º.

I_DEFAULT outside of RSwindows, L_IS_STIX on inside all RSwindows

MTP11 - First Perihelion window: 

MTP11 - First North window: very close to the Sun at a reasonable latitude

MTP11 - Second Perihelion window: 

  • one of the 3 closest perihelion windows, interesting for high-resolution science like R_SMALL_HRES_LCAD_FineScaleStructure (can be run on different targets for example)
  • If it fits TM wise, L_FULL_MRES_MCAD_Flare_SEPs  could be run here as well (depending on what has been scheduled in rest of MTP)
  • L_BOTH_MRES_MCAD_Flare-SEPs to run through this perihelion and upcoming north window: benefits of close distance + radial alignment with Earth. SPP would be big asset as well.

MTP11 - Second North window: 

Alternative plan for full set of second orbit - final 3 RSWs:

  • During this period, from 9 May to 25 June, we can run RS observations with minimal interruption (only 7 interwindow days between the South window and the extension start of the concatenated period).
    SC goes from -21º to +21º passing through one of the closest perihelia. This is particularly interesting for L_BOTH_LRES_MCAD_Pole-to-Pole SOOP.
    TM is low in that MTP period which is OK since this SOOP has quite low TM needs.

MTP11 - First North window: L_SMALL_HRES_HCAD_Fast_Wind duration 3 days - EUI and PHI flush limited volume (still to be set in SOOP)
