Decay of Active regions: see slides in 4-Bellot-Rubio-SAP4_magnetoconvection5_final.pptx:
Decay process of ARs is not well known:
- Slow, may last a few weeks
- ARs approach limb and suffer from projection effects
- Emerging flux starts to reconnect with preexisting flux very soon
- Appearance of filaments, flux rope eruptions and CMEs in late phases of decay
- Sunspot fragmentation by light bridges?
- Flux erosion by convective flows?
- Role of moving magnetic features?
- How is the AR flux dispersed?
- What is the fate of the flux?
Default SOOP duration: 15 days
Pointing requirements: target pointing and tracking
|EUI||EUV & LYA Coronal hole modes (C) 600 s cadence||EUV + Lyman alpha, FOV and resolution matching PHI|
|SPICE Dynamics (bracketed by SPICE Composition Mapping)||2" slit, 128 slit positions, scan duration 11 minutes|
|PHI||PHI_magnetograph_FDT/HRT_2 HRT||Full FOV, 10 min cadence, 5 quantities, 2x2 binning|
|Metis||METIS standard modes: MAGTOP or GLOBAL||Metis can potentially provide context data before and after the 15 day SOOP (offpointing during the 15 days)|
(e.g., orbital requirements, solar cycle phase, quadrature ...)
