Proposed SOOP Coordinators
C. Owen, Hardi Peter, Tim Horbury, Pradeep Chitta (Obj 4), D. Spadaro, A. Giunta, L. Harra, D. Baker
Description
Try to catch with Remote Sensing instruments the dynamics at a open-closed field boundary which will then be crossed in situ. High resolution RS observations required to catch dynamics. This SOOP will in general need specific target pointing or target tracking unless the SC is far enough from the Sun to catch.
Default SOOP duration: 3 days
Pointing requirements: Off-pointing: specific target pointing or target tracking
Triggers: only IS triggers enabled TBC
See SOOP 2 defined for SOWG8 planning exercise.
| Instrument | Mode | Comment |
|---|---|---|
| EPD | close mode + scheduled/triggered burst | |
MAG | normal + scheduled/triggered burst | |
| RPW | normal + scheduled/triggered burst | selective downlink useful |
| SWA | normal + scheduled/triggered burst | |
| SPICE | combination SPICE Dynamics & SPICE Composition Mapping rasters | Raster area should be optimized to make sure open-closed field boundary is captured Line choices optimized for type of target Use observation called SPICE_WIND_CONNECT in modelling. |
| EUI | EUV & LYA Coronal hole modes (C) (uses HRI) at 1min cadence FSI Synoptic mode (S) throughout | If TM is limited, varying priority schema can be used to keep HRI data manageable |
| PHI | Regularly spaced HRT data at medium to high resolution + regular PHI Full-disk Precursors | PHI LL magnetograms needed throughout. Processing after the RSW: PHI could focus downlink on the most interesting periods, as inferred from other LL data |
| Metis | MAGTOP or GLOBAL (see METIS standard modes) for context modelled as GLOBAL with default settings | Only applicable if beyond ~0.5AU during target tracking |
| SoloHI | Context via SoloHI synoptic modes | Model for now as HI_SYN_NEAR |
| STIX | STX_NORMAL | not strictly needed for SOOP although context is appreciated |
| SAP objective | Target | Duration | Opportunity/Orbital configuration | Operational constraints | Additional comments |
|---|---|---|---|---|---|
| 1.1.2.2 Does slow and intermediate solar wind originate from coronal loops outside of coronal holes? | coronal loops outside of coronal holes | few days |
|
| radial alignment with SPP is a plus |
| 1.2.2.6 Study fast plasma flows from the edges of solar active regions discovered with Hinode/EIS | edges of solar active regions - at most likely ballistic connection point | few hours |
|
| radial alignment with SPP is a plus |
Open-Closed field line boundaries (near ballistic connection point):
Target tracking | ~1 RSW (10 days) |
|
| radial alignment with SPP is a plus | |
| 1.2.2.5 Magnetic reconnection in the chromosphere, the transition region and the corona | |||||
| Quiet Sun at various latitudes. | several days | low + high latitue, to be repeated along the cycle |
| Only PHI, EUI/HRI and SPICE really necessary for this goal. PHI/HRT mode 2 with 5-10 min cadence, 5 quantities and no binning EUI/HRT follows cadence of PHI | |
To be discussed whether any of the following can be linked:
1.1.3.1 Fine structures in the photosphere (Full characterization of photospheric magnetic fields)
1.1.3.3 What is the distribution of the open magnetic flux?
1.2.1.7 Detect and characterise waves in closed and open structures

(Andreas Lagg): This SOOP also covers the scientific plan proposed by Hardi Peter: "Solar wind variations on supergranular scales"
