Proposed SOOP Coordinators

A. Giunta, S. Parenti, D. Berghmans, D. Spadaro, A. Fludra, L. Harra, D. Baker

Description

Mapping the abundance of minor ions as a function of height in the corona to distinguish between slow and fast wind. This will be targeted at the boundary of a streamer, or at an active region on the limb. SPICE-led.

Default SOOP duration: 3 hrs

POinting requirements: off-pointing close-in / disk-centre farther out

Triggers: disabled


InstrumentModeComment
EUIHRI observations, e.g. in EUV & LYA Active Region modes (A). Cadence TBD (currently modelled with 360s cadence, i.e. 20.2 kbps)Context and also higher (than SPICE) cadence observations in order to interpret the SPICE composition map

Metis

One of METIS standard modes before main observations, get coronal context, but will not participate at limb pointing (unless s/c at large heliocentric distance): mode TBD
Currently modelled as WIND		Context especially important for streamers
PHI

FDT synoptic data: 1024 x 1024 pixels, at 6 hr cadence

Ic, B, γ, φ

PHI_synoptic_FDT_4 

PHI is needed for context magnetic field, but mainly before or after the SPICE observations as the target will be on the limb!

SPICE Composition Mapping

  • Slit: 6"
    • At larger distances, when possible, use narrow slit (4"), to enhance spatial resolution.
  • Exposure time: 180 s
  • X positions: 60
  • FoV:  6' (or 4') x 11'
  • Observation time: 3 hours per repeat
  • Nº repeats: depends on target

Lines for SPICE Composition Mapping:

– 15 lines (2 profiles+ 13 intensities)

  • Ne VIII 770 Å,

  • Ne VIII 780 Å,

  • Mg IX 706 Å,

  • O II 718 Å,

Additional comments
1.1.2.3 Abundance of minor ions as a function of height in the corona as indicator of slow or fast wind

Limb active region (incl the edges), or streamer boundary at limb

3.2 hours, twiceAny RSW is okay, but perihelion preferred for the AR case, and >0.55AU is preferred for the streamer case (requires Metis compatibility)
put EUI in at least twice the cadence of SPICE to interpret composition map (and possible aliasing in time)
