R_FULL_MRES_MCAD_Polar-Synoptics

General description

This SOOP is designed to observe the entire solar disk while the inclination of the spacecraft relative to the ecliptic plane is greater than 10º. The spacecraft would come from maximum latitude, followed by a slow decrease in latitude (after perihelion). The observations will cover the entire solar disk and will be performed using the synoptic program of the RSW instruments.

The SOOP should start when the spacecraft is around the maximum solar latitude (e.g., around 16.9º for RSW 21 and RSW 27) as part of a RSW and then be continued as a synoptics program (preferred RS-Synoptics-High flavor, where SO/PHI would go to the highest cadence possible depending on TM). This SOOP will enable the monitoring of the magnetic fields over the solar poles for several weeks.

Default SOOP duration: Throughout an entire remote sensing window, starting around maximum latitude and then continuing the SOOP as a synoptics program outside the RSW.

Pointing requirements: disk center

Triggers: disabled

Observations requirement (baseline)

Instrument	Mode	Comment
PHI (lead)	FDT synoptic: PHI_synoptic_FDT_4	Onboard averaging to increase the signal-to-noise ratio; highest possible cadence (preferable 30-60 min) depending of total available TM for the LTP (considering the data can be stored within the instrument and flushed later).
EUI	FSI Synoptic mode (S)	The cadence of RS-Synoptics-High flavor would be preferred, but the cadence of the standard flavor is also fine
SPICE	SPICE Composition Mapping (or alternatively SPICE Dynamics at start)
SoloHI	HI_SYN_MID or HI_SYN_PER
Metis	METIS standard modes: GLOBAL or LT-CONFIG	The cadence of RS-Synoptics-High flavor would be preferred, but the cadence of the standard flavor is also fine (depending on TM)
STIX	STIX Normal Mode	The cadence of RS-Synoptics-High flavor would be preferred, but the cadence of the standard flavor is also fine (depending on TM)

All in situ instruments in Normal Mode.

Additional comments

4.1 How is magnetic flux transported to and re-processed at high solar latitudes?

High Latitudes

several weeks, starting within an RSW and continuing as synoptics

during a period while the latitude is slowly decreasing; post-perihelion RSW and following weeks

Metis compatible as RSW should　be at distances >0.5 au; telemetry as　preferable phase is when　flying towards superior　conjunction
