Full-Disk, high resolution SOOP designed to catch eruptive events.
This SOOP can also be aimed at measuring in-situ SEPs properties and kinetics and linking them to the observing SEPs CME acceleration. To that end, determining the location, timing, and motion of CMEs and shocks is important.
SoloHI and Metis are leading this SOOP, while IS payload provides continuous observations.
Default SOOP duration: 1 day (to 10 days to maximise the possibility to catch an eruptive event)
Pointing requirements: disk centre
Coordination: Can be run when Parker Solar Probe is within 0.25 AU and optimally to the east of SO (to triangulate the CME shocks).
Triggers: enabled for both IS and RS (especially if flare > M5).
Observations requirement (baseline)
METIS standard modes: GLOBAL + CMEOBS on trigger
(modelled as 2 CME events of 1 hr in the 1-day-SOOP)
|CME Trigger on, Disk centre pointing needed|
|SoloHI (lead)||Combination of shock and synoptics at perihelion||Combine HI_SHOCK_PER + HI_SYN_PER (each 50% of time)|
|EUI||Global Eruptive Event Mode: FSI Global eruptive event mode (G)||Triggered:|
FDT, 2-5 minute cadence, highest spatial resolution
|Selection of data so will check LLD|
SPICE Composition Mapping (or alternatively SPICE Dynamics at start,
then SPICE Waves mode (sit-and-stare)
Off-pointing would be interesting for SPICE, but even if disk-centre pointed Composition mapping or Dynamics (both with the maximum SPICE FOV) should be ran before running Waves sit-and-stare.
SPICE_WAVES has been used for modelling SAP v.0
|STIX||Standard Operations: STIX Normal Mode|
|RPW||Detection Mode||Detection algorithms active|
(e.g., orbital requirements, solar cycle phase, quadrature ...)
|22.214.171.124 CME initiation||Full Disk||1 Day (limited by EUI/PHI internal memory)||Perihelion preferred. Quadrature with Earth preferred. Interesting throughout the solar cycle.||No offpointing beyond Metis limit.|
EUI/PHI at highest cadence appropriate to spatial resolution (could be slower if further away). SPICE Sit & Stare in waves mode to try and catch EUV waves.
|126.96.36.199 Where and when are shocks most efficient in accelerating particles?|
Corona + Heliosphere
|Good radial spread.||Good to have Metis compatible|
SWA 5 minutes captures
SoloHI needed for estimating the total CME energy
FSI not needed
|188.8.131.52.1 Intensity variability|
Gradual SEP events
|Preferable with Earth images and SO +/- 70 degrees from Earth-Sun line (probably because gradual events extend up to 100 degrees in longitude)||Metis compatible|
MAG/RPW/SWA not needed
FSI 5 min cadence for source identification (FSI is 10 min cadence by default)
|184.108.40.206 Are there favourable environments for particle acceleration?||Corona + Heliosphere|
FSI 10 min cadence (default)
