LTP14 will run from 2024-01-01T00:00:00 to 2024-03-11T00:00:00 

Orbital context

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.

Definition for the grey shading representing downlink rates:

  • white = maximum downlink rate at which you can empty the SSMM in ~10 days
  • light-grey = SSMM fill state decreases with everyone operating at EID-A rates
  • mid-grey = SSMM fill state increases within RSW (10 instruments operating) and decreases outside RSW (IS-only breakeven rate < downlink rate < inside-RSW breakeven rate )
  • dark-grey = SSMM fill state increases with just IS operating (downlink rate < IS-only breakeven rate)

RS window placement

As agreed during the SWT-36 (April 2023), no RS windows will be placed in LTP-14. The H1-2024  RS windows will all take place in LTP15 Q2-2024.

GAMs and conjunctions

  • No conjunctions
  • No GAM in this period.

Science and calibration planning

Note the text in red highlights adjustments still to be made in SOOP Kitchen plan during Long Term Planning

Coordinated science (and cross-calibration) campaigns:

  • 2024-02-10 to 20 (exact dates TBC): PHI Full Disk Helioseismology campaign coordinated with SDO 
  • 2024-02-27 ±2 days: Full-disk 5x5 mosaic at ~0.7 au distance from the Sun. Slow variant (22-mins dwells) tailored to SPICE.
  • 2024-03-10 (exact date TBC): Full-disk 5x5 mosaic at ~0.55 au distance from the Sun. Fast variant (5-mins dwells) incl. EUI, PHI and SPICE observations.

IS calibrations:

  • 2024-01-25 or 30 (exact date TBC): MAG calibration roll incl. 13 revolutions around Sun-SC axis

RS calibrations:

  • 2024-01-01 to 03: Metis star calibration theta Oph. Continuation from LTP13.
  • 2024-01-24 to 31: Metis star calibration Sigma Sgr during MAG calibration roll.
  • 2024-02-06 (exact date TBC): PHI flatfield calibration, prior to Full Disk Helioseismology campaign (CC_OFFPOI_FLATFIELD_FULL)
  • 2024-03-08 (or later): Co-Alignment calibration (CC_OFFPOI_ALIGNMENT)

IS-only science:

SOOP Kitchen plan

High-level (=MLP) plan:

Starting point for LTP planning in SOWG: to be added after LTP-14 event files have been received from MOC (expected end Sep 2023)

Final plan LTP14: to be added after SOWG review and final consolidation of plan (expected mid Nov 2023)
