Proposed SOOP Coordinators

D. Spadaro, A. Vourlidas

Description

This SOOP is aimed at observing structures in the outer corona and linking them to the heliosphere observed in-situ. Metis and SoloHI are leading this SOOP, while IS payload provides continuous observations. Synoptic support from other full disk RS instruments. Disk centre pointing preferred.

Default SOOP duration: 1 day

Pointing requirements: disk centre

Triggers: only IS triggers active

See SOOP 5 defined for SOWG8 planning exercise.

(SOOP will be modelled with 1 day duration, can be repeated as many times as needed)


InstrumentModeComment
SoloHI
(leads) 
SoloHI combination of high cadence TURB and synoptic mode (model as HI_SYN_NEAR for now)
Metis
(leads) 
Generic program like WIND (METIS standard modes) interleaved with FLUCTS (METIS special modes) (FLUCTS runs 1 hr/day)disk centre pointing preferred

PHI

FDT synoptic: PHI_synoptic_FDT_4PHI may be processing in between observations. all data gets downloaded
EUIFSI synoptic: FSI Synoptic mode (S)all generated data gets downloaded

SPICE
(optional)

SPICE currently proposes to use either SPICE Limb mode or SPICE Dynamics, depending on requirement for Metis-compatibility

Limb target (not Metis-Compatible; SPICE Limb mode) :

  • Slit: 4"
  • Exposure time: 5 s
  • X positions: 224
  • FoV: 15' x 11'
  • Nº repeats: 10
  • Observation time:
    • 18 mins per study
    • 3.2 hours total.

Active region, if before or after Metis observatiosn (SPICE Dynamics) :

  • Slit: 4"
  • Exposure time: 60 s
  • X positions: 128
  • FoV: 8.5' x 11'
  • Nº repeats: 1?
  • Observation time: 2.1 hours
  • Limb active region target best if present. Cannot participate if Metis is observing

Lines for SPICE Limb mode:

  • H I 1025 Å,

  • C III 977 Å,

  • O VI 1032 Å,

  • Ne VIII 770 Å,

  • Mg IX 706 Å,

  • Si XII 520 Å (2nd order) 

– 3 profiles and 3 intensities.


Lines for SPICE Dynamics:

  • 4 profiles and 6 intensities.




SPICE contribution is important for the measurements of line profiles, whose broadening can be considered a signature of the presence of waves in the atmosphere. SPICE observations near the limb can be carried out soon before and after those of Metis.

Metis needs to see within 5RS for Lyα

Metis not strictly needed for this one but could still provide useful context.
